Worst kind of cancer. Cancer from a to z in simple words, we will analyze without embellishment. Why coffee works as a laxative and diuretic

Every year, malignant tumors claim the lives of more than 1 million people, and the inexorable WHO statistics claim that oncology is main reason 14% of all deaths. In other words, every 8 people in the world die of cancer!

What is the danger of the disease

So far, no cure for cancer has been found. What is the snag? At the heart of a cancerous tumor are cells that develop differently than the rest. Their abnormal growth is considered malignant to the health of the body. The tumor is formed very quickly, and in relation to healthy tissues and organs behaves like an aggressor. With the help of blood, lymph or nerve pathways, its cells are carried throughout the body to initiate a metastasis - a daughter tumor.

It is the process of metastasis that sometimes leads doctors to a dead end: the faster the tumor grows and metastasizes, the more difficult it is to save the patient.

What type of disease is most difficult to treat

Each type of tumor is considered less or more dangerous depending on the degree of its malignancy. Cancer is considered less aggressive and well treatable if abnormal cell division occurs slowly and metastases do not spread rapidly throughout the body. The rapid growth of the tumor and the rapid spread of metastases are dangerous for human life, because they are difficult to treat.

What is the most serious type of cancer and why?

Melanoma, or skin cancer

The queen of tumors and, at the same time, a rather rare type of pathology. The disease is of an extremely aggressive nature and the patient has practically no chance of recovery - metastases appear very actively throughout the body. Surgical intervention can stop the development of the disease for some time, but only at its initial stage.

Melanoma is easy to diagnose, as it is located on the surface of the skin, but, no matter how paradoxical it may sound, it is often detected only after the formation of daughter tumors. The fact is that at first the neoplasm does not differ from an ordinary small mole, therefore it does not bother a person at all. Remember: if colored asymmetric spots with blurry edges begin to appear on the skin, undergo a medical examination.

Lung cancer

This form of the disease is very dangerous, according to many doctors. Every year it causes the death of about 1.5 million people. Science has long discovered a direct link between lung cancer and the most "popular" bad habit of our time, smoking. For a long time, the disease may not manifest itself. The only signs are that the patient coughs violently and suffers from bronchitis and pneumonia more often than before. In most cases, lung cancer is diagnosed too late, and treatment does not bring the expected results.

brain cancer

The disease is very dangerous due to the place of its localization. The brain is protected by a strong cranium, therefore, it is extremely difficult to act directly on the tumor focus, and any surgical intervention potentially fatal to the patient. Any neoplasm in the brain, even a non-aggressive one, is obviously malignant, because it compresses the structures of the brain and destroys them after a while.

Pancreas cancer

It occurs frequently, but is difficult to treat. Surgery is associated with a high risk of death and does not always bring a positive effect. This type of disease is very insidious - for a long time it develops without any external symptoms.

Leukemia, or blood cancer

Oncology destroys the bone marrow, which loses its ability to produce full-fledged blood cells. Leukemia is caused by just one mutated hematopoietic cell. This form of cancer is the most common among childhood cancers.

Lymphoma, or cancer of the lymph nodes

The disease destroys the human immune system, the main active elements of which are the lymph nodes. Cancer inflicts the strongest blow on the body, bringing it into a state of profound immunodeficiency.

Have you noticed that almost all types of cancer have common feature? They skillfully "disguise" themselves as a common ailment, so a person seeks help too late! The conclusion is obvious: one should treat one's health as the greatest value in the world, and promptly respond to all alarm signals of the body.

This disease has not yet been fully studied, and thousands of scientists daily direct their efforts and knowledge to the invention of more and more new methods of dealing with it.

Let's see what are the most common types of malignant neoplasms that exist in the world. After all, the better we know the enemy by sight, the faster we will repulse him.

Types, statistics and symptoms of cancer

- Cancer of the lungs and bronchi

The most common cancer in developed countries. It is a serious medical and social problem. About 1 million new cases of lung cancer are registered annually in the world.

The main symptoms of lung cancer:

Prolonged cough;
Hemoptysis;
Dyspnea;
Pain in the chest.

- Cancer of the colon and rectum

It is the cause of not only high mortality, but also significantly worsens the quality of life of many patients. More than 500,000 cases of this type of cancer are diagnosed annually.

The main symptoms of colon and rectal cancer are:

diarrhea or constipation;
Blood in the stool is a change in its character and density.

- Mammary cancer

Takes the lives of hundreds of thousands of women around the world. From 800 thousand to 1 million new cases are registered annually. Every woman should once a month independently examine her breasts for the presence of formations in it. After all, early detection of this form of cancer gives a very high guarantee for successful treatment.

The main symptoms of breast cancer:

The presence of a lump in the chest;
Nipple retraction;
Bloody discharge from the nipple;
Changes in the skin of the chest according to the type of "orange peel".

- Pancreas cancer

A fairly aggressive form of cancer. Every year about 220 thousand of this disease are registered in the world. Of these, 213 thousand end in death.

The main symptoms of pancreatic cancer:

Pain in the left hypochondrium;
Yellowness of the skin.

- Prostate cancer

It occurs in every seventh man over the age of 50. Therefore, all doctors insist that every man, upon reaching this age, undergo an annual preventive examination by a proctologist. This will significantly increase the chances of success in treatment.

The main symptoms of prostate cancer:

Frequent urination or frequent "false" urges;
Urinary retention or difficulty in urination;
Soreness in the perineum.

- Leukemia

The most common form of cancer occurring in childhood. It is because of the immaturity of the hematopoietic system that it often affects children and young people. In Europe, there are 3-4 cases of leukemia for every 100,000 children.

The main symptoms of leukemia:

Fast fatiguability;
Insomnia;
Paleness of the skin;
Nosebleeds, bruising that does not go away for a long time;
Frequent sore throats;
Inflammatory diseases of the oral cavity;
Persistent fever for no apparent reason.

- Non-Hodgkin's lymphoma

A malignant disease that affects children, adolescents and, most of all, the elderly. With age, the risk of developing non-Hodgkin's lymphoma increases significantly, especially in people who are exposed to many carcinogenic factors throughout their lives. According to statistics, among the inhabitants of Europe, for every 100 thousand people there are 12-15 cases of this disease.

The main symptoms of non-Hodgkin's lymphoma are:

Enlarged lymph nodes;
Unreasonable rise in temperature;
night sweats;
Stomach ache;
stool disorder;
Paleness of the skin.

- Liver cancer

Also one of the most common forms of cancer in the world. It is dangerous because it arises not only as an independent neoplasm, but also begins to develop, hitting the liver with blood flow from existing tumors. At least 250,000 people develop this type of cancer every year worldwide.

The main symptoms of liver cancer:

Malaise;
Nausea;
Vomit;
Aching pain in the right hypochondrium and a feeling of heaviness in the same place.

- Ovarian cancer

It is the leading cause of death from gynecological diseases, the fifth leading cause of death among women from oncology. It also ranks second among oncological diseases in gynecology.

The main symptoms of ovarian cancer:

Drawing pains in the lower abdomen;
In the later stages - an increase in the volume of the abdomen.

- Esophageal carcinoma

It is the cause of 900 thousand deaths from oncological pathology annually worldwide. Approximately 70 percent of patients die within 1 year of diagnosis.

The most dangerous types of cancer

Cancer is one of the most dangerous and widespread diseases in the world. Every year they provoke the death of more than 1 million people. According to statistics from the World Health Organization, cancer is responsible for 13% of all human deaths, in other words, every 8th person dies from this disease.

Cancer is a scourge modern society for which no 100% cure has yet been found. What is this disease? Cancer is a disease in which the cells of the body begin to grow abnormally, thus forming tumors, which in turn affect the activity of other and affected organs. In this case, the tumor is called malignant. But the main trouble is that the process of tumor maturation itself is very fast, and in most cases the cells of this tumor are aggressors in relation to other organs and tissues. These cells can invade and spread with the flow of blood, lymph or nerve pathways, settling in other parts of the body and thus giving rise to a new, daughter tumor - metastasis. This process itself is called metastasis. It is the main reason why cancer is so poorly treated. Exactly fast growth tumor and its ability to metastasize determines the degree of cancer malignancy.

Each type of cancer differs in the degree of malignancy. Low-grade cancers are less aggressive, heal slowly, metastasize slowly, and generally respond well to treatment. Cancer with a high degree of malignancy is prone to rapid growth and the rapid formation of metastases.

Among the most dangerous types of cancer are lung cancer, melanoma, brain cancer, pancreatic cancer, leukemia and lymphoma.

Lung cancer is the most scary view cancer according to many doctors. The number one cause of death from cancer. Every year, more than one and a half million people die from this disease. The peculiarity of this disease lies in the fact that in most cases, although not in all, it is caused by smoking, that is, a disregard for one's health by the person himself. Lung cancer may not show up for a long time, except for a severe cough and a tendency to bronchitis and pneumonia. Who has not heard about the dangers of smoking?

Melanoma is the rarest type of skin cancer, which is called the queen of tumors. An extremely aggressive type of disease, it forms metastases very quickly and is practically not amenable to any treatment other than surgery, but this only has an effect on early stages. Although melanoma is easy to diagnose (because it is located on the surface of the skin), often the diagnosis is made when daughter tumors have already formed. The problem is that the tumor is no different from a small mole and does not attract much attention until the disease has gone far enough. Having found suspicious birthmarks on the body, it is better to immediately take precautions and get checked.

Brain cancer is dangerous due to its location. Since the brain is protected by the skull, it is very difficult to get to the tumor that has formed in the head. Surgery carries a high risk of death. A feature of brain tumors is that absolutely any tumor in the brain, be it non-aggressive, is malignant, as it causes compression of the brain structures, and then their destruction.

Pancreatic cancer is quite common and very difficult to treat. Surgical intervention is possible, but is accompanied by high risks and is not always effective. A feature of this type of cancer is that it develops for a very long time without any symptoms.

Leukemia - leukemia, leukemia, blood cancer. A disease that affects the bone marrow, which thereby loses the ability to produce normal blood cells (blasts). Leukemia is caused by a mutation in a single hematopoietic cell. This disease is number one in pediatric oncology.

Lymphoma is cancer of the lymph nodes that protect the body from disease. In a word, cancer of the human immune system. It is immediately clear what the main danger of this disease is. This type of cancer weakens the human body more than any other type. In fact, lymphoma is an immunodeficiency.

The most dangerous types of cancer

Malignant tumors are one of the most common diseases on the planet, every year they find millions of new victims. Cancer is responsible for 13% of all human deaths, in other words, every eighth person in the world dies from this disease.

What is this disease and what exactly is its danger?

In a nutshell, cancer is a disease in which a group of cells begins to grow uncontrollably, and so quickly that they do not have time to mature. A tumor is a random heap of immature cells, which are also aggressive - they invade adjacent tissues, destroying them, or they can break away from the main tumor and spread through the blood, lymph or nerve pathways, settling in other parts of the body and giving rise to a new one, daughter tumor. This process is called metastasis, and daughter tumors are called metastases. Metastasis is one of the main reasons cancer is so difficult to treat. The rate of tumor growth and its ability to metastasize determines the degree of cancer malignancy.

Different types of cancer differ in their degree of malignancy. Cancer with a low grade of malignancy is less aggressive, the disease proceeds slowly, metastases do not form for a long time, and in general this type of tumor has a favorable prognosis, as it responds well to treatment. Tumors with a high degree of malignancy metastasize early and are prone to rapid growth. Such aggressive tumors require the most active treatment possible, since the margin of time is very limited. The degree of malignancy depends on many reasons, the main of which is the degree of maturity of the tumor cells and what kind of cells they are.

Melanoma

Melanoma, the rarest type of skin cancer, is called the queen of tumors. This is an extremely aggressive type of cancer, which very quickly gives multiple metastases and is practically not amenable to any treatment other than surgery, and even then it is effective only until the tumor has had time to spread throughout the body. Although melanoma is easier to diagnose because in most cases, although not always, it is visible due to its superficial location, often the diagnosis is made only when it has already metastasized. The reason is that the tumor is almost no different from a small mole and does not attract much attention until the process has gone far enough. Suspicion should be caused by moles that appeared in adulthood, very black or having a heterogeneous color, dense and small, without hairs. Having found such a “birthmark” spot, it is better to take precautions and get checked, because the sooner the tumor is detected, the greater the chance of recovery.

Lung cancer

Lung cancer is the number one cause of death from cancer in the world. Almost one and a half million lives are claimed annually by this malignant disease. Its peculiarity is the fact that most cases of lung cancer, although not all, are directly related to smoking, that is, they are caused by a disregard for one's health by the person himself. Who has not heard about the dangers of smoking? There probably aren't any. Which smoker is sure that this will not affect him in any way? One hundred percent out of a hundred.

Lung cancer does not manifest itself in any way for a long time, except perhaps for a persistent cough and an increased tendency to bronchitis and pneumonia, but these signs appear already at advanced stages, and smokers do not pay attention to cough until it becomes painful and permanent. Often this alarming sign is evidence that cancer has already captured the lung.

brain cancer

Brain cancer is very dangerous because of its location. The brain is "hidden" in the skull, which serves as its protection, but in the case of a tumor, this factor plays a negative role - it is difficult to get close to it, surgical intervention is associated with high risks of damage to vital brain structures, because, in fact, there are no unimportant ones there. Tumor growth in a closed cranial space inevitably causes compression of neighboring brain structures, and then their destruction. That's why, without exception, all brain tumors are all considered malignant - they all lead to death if they are not removed on time. Unfortunately, this type of tumor is often found in children.

Intense headaches, aggravated in the morning and with a change in body position, nausea, vomiting without dysfunction gastrointestinal tract- those symptoms in which you need to immediately go for examination.

Pancreas cancer

A fairly common type of cancer, about 42.5 thousand new diseases are diagnosed in America every year, and more than 60 thousand in Europe. This type of tumor is extremely difficult to treat, surgery is possible, but involves significant difficulties and is not always effective, and in addition, pancreatic cancer develops for a long time without any special symptoms at all. A small habitual ailment in the form of wandering pains in the abdomen and back is in no way associated with either cancer or the pancreas, and the first serious signs often appear when there is nothing left to save.

Leukemia

Leukemia, it is also leukemia, it is also leukemia, it is also blood cancer - a malignant disease that affects the bone marrow, which gradually loses the ability to produce normal blood cells, filling with immature aggressive cells called blasts. Blasts are unable to perform the functions of blood cells, instead they only grow rapidly. Normal blood cells have a limited lifespan, when they are destroyed, they must be replaced by new ones that have matured in the bone marrow, and the number of those gradually disappears, being replaced by blasts.

Leukemia is caused by a mutation in a single hematopoietic cell. Children often suffer from leukemia, this disease is number one in pediatric oncology, acute leukemia is common in children. Acute and chronic leukemia are not two forms of the same disease, but two different diseases that never pass one into the other. Both forms are deadly, but, oddly enough, children with acute leukemia are more likely to succeed, of course, with active treatment.

Lymphoma

Lymphoma is a cancer of the lymph nodes - organs of the immune system designed to protect the body from diseases, including malignant tumors. Therefore, it is clear that the defeat of this particular system is a mortal danger to the body, as it weakens it more than other types of cancer. In essence, lymphoma causes immunodeficiency, a condition in which the body loses its immune defenses, similar to AIDS. Lymphomas are extremely diverse, including varying degrees of aggressiveness. Some of them, called indolent ones, can develop very slowly, for decades, while others can kill a person in a matter of weeks. Enlarged lymph nodes, weakened condition, night sweats - these are the meager symptoms of lymphoma, which is not only diagnosed late, but also difficult to treat.

10 deadliest types of cancer and why they are not treated

The horror and fear that come to a person when he hears such a diagnosis can hardly be compared with anything. This is the number 2 cause of death among Americans, the primacy in this terrible category is occupied by cardiovascular disease. Even with early diagnosis and treatment with the latest methods, it still has the power to kill a person.

Despite the fact that today there are such new methods of treatment that nothing was known about a few decades ago, the "cure for cancer" is still something that is still unattainable by science. There are about 100 types of cancer, as well as many causes that contribute to its development, ranging from radiation to various viruses and exposure to carcinogens.

Cancer cells, as well as the direction of their growth, are still unpredictable, and in some cases this process is generally mysterious. Even after it seemed effective treatment, cunning cancer cells can still make themselves felt.

About $200 billion has been spent on cancer research since the early 1970s, with patient survival rates rising from 50 percent to 65 percent.

“Today, we wouldn’t know so much about cancer if basic clinical science research hadn’t been funded,” says Dr. Len Lichtenfeld, one of the American cancer. “Basic science tells us about how drugs work and how effective drugs can be, we absorb that information and put it to the test.”

Below are the 10 cancers that killed the most people in the United States between 2003 and 2007, according to the National Cancer Institute.

1. Bronchial and lung cancer:lifetimes

This type of cancer is the worst killer of people in the United States. Smoking and the use of tobacco products is the main cause of its development, which most often affects people of age. There are two main types of lung cancer: non-small cell lung cancer, which is the most common, and small cell lung cancer, which progresses much faster. More people are expected to die from bronchial and lung cancers in 2010.

2. Colon and rectal cancer: life

According to the National Cancer Institute, colon cancer develops in the tissues of the colon, while rectal cancer develops inches from the colon. In most cases, cancer begins as a collection of small, benign tumors called polyps that become cancerous over time. It is recommended to undergo regular screening to detect polyps before they turn into malignant tumors. Colorectal cancer is predicted to take the lives of people in 2010.

3.Breast cancer:Life

Breast cancer is the second most common cancer among women in the US after skin cancer. But this type of cancer also occurs sometimes in men, in the period from 2003 to 2008, about 2,000 cases of breast cancer were recorded in the stronger sex. Usually, this species cancer develops in the channels that carry milk to the breast, or in the glands that produce it. According to forecasts, people will die from breast cancer in 2010.

4. Pancreatic cancer:lifetime

This type of cancer begins to develop in the tissues of the pancreas, which helps digestion and is involved in the regulation of metabolism. It is extremely difficult to detect it in its early stages, as it often progresses quickly and imperceptibly. According to sad forecasts, this type of cancer in 2010 will take the lives of people.

5. Prostate cancer:lifetime

According to statistics, this type of cancer is the second most common cause of death among men after lung and bronchial cancer. Typically, cancer begins slowly in the prostate gland, which produces seminal fluid for "transportation" of sperm. Some types of this cancer are limited to the prostate gland and do not spread further, which makes it easier to treat, while others, on the contrary, are more aggressive, as a result of which cancer cells begin to colonize the entire body. In 2010, prostate cancer will kill about men.

There are many types of this cancer, but each affects the body's blood-forming tissues, namely the bone marrow and lymphatic system, resulting in the production of abnormal white blood cells. Leukemia is classified by how quickly it progresses and which cells it affects. A type called "acute myeloid leukemia" killed the most people during the period under review (41,714 people). Nearly a person is predicted to die of leukemia in 2010.

7. Non-Hodgkin's lymphoma: lifetime

This type of cancer destroys lymphocytes, the white blood cells, and is characterized by severe enlargement of the lymph nodes, fever, and weight loss. There are several types of this cancer, which are classified according to the rate of progression of the disease, as well as which type of lymphocyte is affected. Non-Hodgkin's lymphoma is a very merciless disease that is predicted to claim human lives in 2010.

8. Cancer of the liver and intrahepatic bile ducts: life

Liver cancer is one of the most common forms of cancer worldwide, but is quite rare in the US. However, in last years the disease is on the rise. Most often in the United States, this situation is observed: cancer begins to develop in another part of the body, and then spreads to the liver. Very close in symptoms to liver cancer and cancer of the intrahepatic bile ducts, which develops in the channels that carry bile from the liver to the colon. According to forecasts, in 2010 this type of cancer will take the lives of almost Americans.

9. Ovarian cancer:lifetime

Ovarian cancer is the number 4 cause of death among American women. The average age of a woman who is diagnosed with a similar diagnosis is 63 years. Cancer is easier to treat but harder to detect in its early stages. However, recent research in this area has shed light on some early symptoms which can provide indispensable assistance in early diagnosis. These symptoms include discomfort in the lower abdomen, frequent pelvic pain, and frequent urination. The year 2010 is predicted to take the lives of women suffering from ovarian cancer.

10. Cancer of the esophagus: lives

This type of cancer begins in the cells lining the esophagus (the tube that carries food to the stomach) and tends to occur most often in the lower part of the stomach. Dying from this type of cancer more men than women, and in 2010 it is predicted to kill a man.

A cancer diagnosis sounds like a death sentence, and it's very hard to change that. This disease is firmly connected in our minds with death, and when cancer overtakes a person, the news of this often demoralizes both the patient and his loved ones. Only the strongest is able to immediately begin the fight against the disease, and how many of those who doomedly fold their hands and submit to fate, believing that this is the only way to exist for the coming months or, if you're lucky, a few years.

Meanwhile, the 200 types of cancer known to science are not the same, and the first weapon against the disease is awareness. It is important to know which types of malignant tumors can be successfully treated at an early stage, what symptoms you need to pay attention to, how often you need to visit specialized specialists in order to exclude an unfavorable development of the situation.

3. Another type of cancer that can be cured in the early stages is skin cancer. The three most common types are basalioma (a basal cell carcinoma that develops from the basal cells of the skin epithelium), squamous cell carcinoma (squamous cell carcinoma), and melanoma. The vast majority of skin neoplasms are basaliomas and squamous cell carcinomas, which, as a rule, do not metastasize to other tissues and organs, but if not treated in time, they can leave noticeable marks on the skin.

Melanoma is a dangerous type of cancer, but it is much less common than the first two. Through the lymph and blood, it can metastasize to almost all tissues and organs. However, early detection a large number of cutaneous melanomas can be treated surgically.

In order to see a doctor in time, it is important to know the signs of the disease. You need to pay attention to moles or dark spots on skin that changes size, shape, or color over weeks or months. Signs of malignancy may include:

- Asymmetry - the two halves of the mole look different;
- The shape of the mole is incorrect, the borders are fuzzy, uneven, blurry.
- The color is uneven, has two or more shades.
- The size of the mole is more than 6 millimeters in diameter.
- A growth, a sore, a pimple that does not heal.
- Bleeding or flaky mole.
- Itching in the area of the mole, hair loss from its surface.

Summarizing, we can say: no matter what skin changes bother you, you should definitely consult a doctor.

4. One of the most common types of cancer in men is prostate cancer. With early diagnosis, when the tumor has not gone beyond the gland, the chance of recovery is 95%. The disease can be asymptomatic, so men, especially the elderly, also need to see a doctor regularly. A urologist can suspect a neoplasm in the prostate gland during the examination. For diagnosis, a blood test, X-ray and ultrasound are used.

However, prostate cancer is not always asymptomatic. Here are the disorders that may be signs of the disease:

- Frequent urination, including at night.
- Painful urination and ejaculation.
Feeling that the bladder is not completely emptied after urination.
- Blood in urine or semen.

The above symptoms can be a manifestation of not only cancer, but also a benign tumor or infectious disease, but in any case, an accurate diagnosis should be made by a doctor after an examination.

5. Next in line is testicular cancer. Unlike prostate cancer, which is more common in older men, testicular cancer affects men over the age of 15, and the average age of the diseased is 40. Signs of the disease are testicular enlargement, hardening, pain in the scrotum or lower abdomen. Pain, however, is not mandatory, so self-examination is the most important measure for early diagnosis. A man should monthly examine and palpate the scrotum and, if in doubt, consult a doctor. The doctor conducts a comprehensive diagnosis, including a blood test, an ultrasound examination and, if a neoplasm is detected, a biopsy.

The main treatment for testicular cancer is surgery to remove it. The surgical method is usually used in combination with chemotherapy and radiation therapy. With timely treatment, testicular cancer can be overcome. According to British statistics, more than 96 percent of the inhabitants of the country with such a diagnosis, who underwent treatment a decade ago, are still alive, and they did not experience a relapse of the disease during this period, which actually indicates a complete cure, since the risk of the disease returning is minimal.

6. Colorectal cancer, that is, cancer of the colon and rectum, is also curable. It usually affects people over the age of 40, in 85% of cases - after 65. Treatment is successful in 9 cases out of 10, but only if the disease is detected in a timely manner, so it is very important to know its symptoms. You need to see a doctor if the following violations observed for several weeks:

It is generally accepted that colon cancer develops from benign polyps. These potentially malignant neoplasms develop on the intestinal wall, and gradually increase in size, turn into cancer. Unfortunately, polyps and early-stage cancers do not always produce severe symptoms, and therefore, after the age of 50, a colon examination should be scheduled. There are several methods for diagnosing colorectal cancer: a doctor's examination, a fecal blood test, a colonoscopy (examination using illuminated tubular instruments), and an irrigoscopy (X-ray). For those who have close relatives diagnosed with polyps or colon cancer, it is better to have an examination at the age of 40 years.

The main treatment for colorectal cancer is surgery. In addition, radiation therapy and chemotherapy are used. As mentioned above, early intervention gives a high chance of full recovery, but this chance drops to 50% or less if the cancer is diagnosed in the later stages.

The described six types of cancer have the most favorable prognosis, however, a cure is also possible with other malignant diseases, such as leukemia, lymphoma, lung cancer, and pancreatic cancer. In any type of malignancy, early diagnosis is important, and this is an area in which a real breakthrough was made in 2012.

15-year-old American student Jack Andraka (Maryland, USA) invented a tester that allows you to diagnose pancreatic, lung and testicular cancer in the early stages by analyzing blood or urine. The tester is based on paper for diabetic tests. The method is 168 times faster, 26,667 times cheaper (when mass-produced, it will cost no more than 3 cents), and 400 times more sensitive than previous testing methods. Let's hope that this method will soon be widely used.

Malignant tumors have a significant distribution. It is from cancer that thirty percent of all dead people die in a year.

Cancer is the uncontrolled growth of cells. In this case, the cells grow so fast that they simply do not have time to mature. As a result, a conglomerate of immature cells, aggressive in nature, is formed. Cancer treatment is widely practiced.

They begin to actively penetrate into all neighboring tissues, are carried with the blood and lymph throughout the body. They form new colonies in other parts of the body, which are called metastases. Actually, it is metastases that significantly complicate the treatment of cancer.
The growth rate of a malignant tumor and the activity of metastasis determine the degree of malignancy of the disease. Diseases with a low malignancy rate are treated quite effectively because they do not have metastases and grow slowly. A high degree of malignancy leaves little or no chance of a favorable outcome. For this reason, it is very important to start treatment as early as possible, because the bill goes not even for months, for days.
The following types of cancer are difficult to treat and are considered the most aggressive:
Melanoma. This is one of the types of skin cancer. It is rare, but its aggressiveness is unparalleled. Melanoma metastasizes very quickly. This cancer can only be treated with surgery. No drugs give a positive effect. But the operation does not guarantee that the disease will stop. As a rule, the disease by that time is already rapidly spreading throughout the body.
Melanoma is very difficult to detect. The fact is that outwardly it is very similar to an ordinary mole. However, upon closer inspection, it turns out that it is black. Melanoma never has hairs.
Lung cancer. Causes the most deaths. One and a half million people die from lung cancer every year on the planet. Although the disease can appear as a result of smoking, this is not the main cause.
The treatment of lung cancer is very difficult. The fact is that in the early stages the disease does not manifest itself. Unless there may be an increased cough, bronchitis and pneumonia. However, these signs appear even then, the disease has gone very far. In fact, a strong cough becomes a sign that the cancer has completely captured the lung. That is, doctors already have to treat late forms of lung cancer with multiple metastases. The prognosis in this case is negative.
Brain cancer. A very dangerous species. The fact is that it is impossible to effectively treat brain tumors due to the physiology of our body. Any drugs are not effective here. The active substances do not reach the brain because they are stopped by the blood-brain barrier. Surgical treatment is also almost impossible, since there is always a danger of damaging vital structures.

An increase in the tumor in any case causes a deterioration in the person's well-being, as there is compression of neighboring areas of the brain tissue. Unlike tumors in other human organs, brain tumors are always considered malignant. The treatment of brain cancer is extremely difficult. There are few cases of successful outcome.
Pancreas cancer. It has become more and more common lately. Experts attribute this to the deterioration of food quality and poor quality environment. Treatment of pancreatic cancer is complicated by structural features and the fact that the disease can develop asymptomatically. People do not attach importance to wandering pains in the abdomen and back. And when it becomes clear that there is a problem, the treatment becomes ineffective. There is nothing to save. Instead of a pancreas, a decaying tumor and metastases throughout the body.
Leukemia. This cancer is also called leukemia or blood cancer. In fact, it is not the blood that is affected, but the bone marrow, which is responsible for the production of blood cells. The affected hematopoietic organ begins to produce blasts - immature blood cells, which are gradually completely replaced by good blood cells.
This disease is very common in children. There are acute and chronic leukemia. It's not the same disease different forms. These are two different diseases. However, both are deadly. True, acute leukemia is easier to treat. Treatment of this cancer today is carried out quite successfully.
Lymphoma is the last type of cancer that we will look at today. As the name implies, it primarily affects the lymphatic system. As you know, this is one of the most important systems human body. Problems with her are deadly. In fact, lymphoma is very similar to AIDS in its action. It also deprives a person of immunity. There are many types of lymphoma. All types are difficult to treat.

This is a form of breast cancer that is difficult to treat. In 10-15% of cases, this tumor is resistant to hormone therapy. Such malignant neoplasms, as physicians note, are especially aggressive, and attempts to treat them end in a relapse of the disease.

The research was conducted by scientists from the University of Lund, who developed a new therapy. They noted that most of such a tumor consists of degenerate cells of the connective tissue, which ensures its development.

Experts have identified the presence of growth factor PDGF-CC in malignant cells, its presence was associated with an unfavorable prognosis. Swedish scientists have found that it is this compound, which is produced by connective tissue cells, that contributes to the formation of resistance to hormone therapy.

Doctors with the help of the drug they created managed to block the connection between malignant cells and connective tissues. As a result, the sensitivity of cells to treatment was restored, writes EurekAlert!

The site reported on a unique new generation vaccine that almost completely destroys cancer cells. Developed by American scientists, the drug activates the immune system to fight the tumor.

The vaccine makes the body's immune cells effectively fight the cancer. It appeared as a result of research by a group of scientists from Harvard University.

As experts explained, the therapy is based on the so-called neoantigens. These are defective peptide molecules that cover the outer shell of cancer cells. The drug helps T-lymphocytes to detect cancer cells by these molecules. As a result, a persistent immune response is observed that destroys malignant neoplasms.

Tests conducted on mice have shown that such drugs are much more effective than conventional ones. For example, a vaccine containing the E7 peptide associated with cervical cancer contributed to the almost complete destruction of this type of tumor. Injected rodents lived for more than 150 days, and treated animals traditional way, died on the 30th day.
