Cancer, Causes And Features

According to statistics collected with the participation of physicians, this year about 10 million people living on the planet will face a terrible, frightening diagnosis - "cancer." However, it is believed that the cancer is fully treatable - albeit under certain conditions and circumstances, but still subject to.

Only 5-10 percent of all cases of cancer can be caused by any genetic defects. The remaining 90-95 percent fall on the causes and risk factors of cancer, which lie in the style of life and the environment. To such factors, scientists include cigarette smoke, diet (fried foods, red meat), alcohol, exposure to sunlight, pollution, infections, stress, overweight, lack of physical activity.

According to the medic, almost every third death from cancer was caused by smoking, as well as caused by the wrong diet, 15-20 percent were caused by infections, and the rest were due to radiation exposure, stress, lack of physical activity, environmental pollution and so Further. As a consequence, the first step in fighting cancer is to stop smoking (or the maximum possible restriction), increase the proportion of fruits and vegetables in the diet, moderate alcohol consumption, diet caloric control, exercise, vaccination and, most importantly, regular condition checks Health.

Cancer is a disease in which healthy cells begin to grow unchecked. As a consequence, eventually a tumor forms. If you leave the tumor without treatment, then the problem can and probably worsen:

• The tumor will spread to adjacent healthy tissue.
• The tumor will squeeze the internal organs.
• A tumor will release metastases that will spread through the lymphatic or circulatory system.

To date, more than two hundred different types of cancer are known. This abundance is due to the number of different types of cells in the human body, which are also more than two hundred. For example, in the lungs can develop lung cancer. However, the lungs consist of different cells, and therefore different types of cancer can develop there .

And although the cells in the body are very different in structure and function, on the whole they are similar. In the center of each cell is a nucleus, inside which is the genetic information, the transferred genes. Genes control the cell, they "decide" when it begins to share what to do and when to die. And, as a rule, the cells divide and grow according to a strictly defined principle. If something suddenly goes wrong - the result, as a rule, is one: the cell dies. However, it sometimes happens that the given system stops working as it should, and then the diseased cell continues to divide, which leads to the formation of a tumor.

Tumors can be either benign or malignant, which is determined by their ability to metastasize. Benign tumors :

• Slowly growing.
• Do not metastasize.
• Covered with healthy cells.

Malignant tumors consist of cancer cells.

• They grow fast.
• They destroy the surrounding tissues.
• They metastasize.

It is the ability to metastasize and makes cancer so dangerous. If you do not start treatment for cancer, it will inevitably spread to organs located near the site of the initial localization of the tumor and cause serious damage to health - even to death.
