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,. 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 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 tend to grow rapidly.. 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..

MelanomaMelanoma, 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, are very black or have 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 cancerLung 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 are probably none. Which of the smokers is sure that this will not affect him in any way? One hundred percent out of one hundred.

Lung cancer does not particularly manifest itself for a long time, except 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. Often this warning sign is evidence that cancer has already invaded the lung..

Brain cancer Brain cancer is very dangerous due to its location. The brain is " Tumor growth in a closed cranial space inevitably causes compression of neighboring brain structures, and then their destruction.. This is why, without exception, all brain tumors are 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 of the gastrointestinal tract - those symptoms in which you should immediately go for an examination.

Pancreatic 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 slight 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, aka leukemia, aka leukemia, aka blood cancer, is 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..

Essentially, 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..
