Someone from the medical scientists said that oncology is the plague and cholera of the present time, and it is difficult not to agree with him. Cancer for its destructive power is in the first three diseases with a fatal outcome. According to health statistics of European countries and the United States, 15-20% of deaths are associated with oncological diseases. And what are the causes of the appearance and development of cancer, let's talk in this article.
What is cancer and why is it called that?
But before we deal with the causes of cancer, let's find out what this attack is, and why it is called that way. Of course, cancer cancer with a river's namesake has nothing to do. And he received his name because of the most frequent form of malignant growths, similar to that of a claw.
In general, cancer is a deviation in the cell at the genetic level. It looks like this: it lives for itself, for example, a liver cell, performs its usual function of producing bile and purifying blood, and suddenly it is influenced by some extraneous force, which brings failure to the normal structure. The cell does not understand what to do next, but in normal other protective forces quickly clean out such a knocked out cells. They simply destroy them, and the body functions as it should. But it happens that the defense did not work, and then the "uncomprehending" cell becomes a draw, and eventually develops into an oncological cell.
Causes of cancer
What affects the failure of the body, leading to such disastrous consequences? In fact, the causes of cancer are great, but they can all be divided into 4 main groups.
- Physical factors. This includes radiation, excess ultraviolet, and much more. Influencing our body during a decrease in immunity, chronic fatigue, etc. these factors may well cause the development of oncology, both benign and malignant.
- Chemical. Chemical factors undoubtedly include the carcinogens that we consume from overcooked and smoked food, as well as foods harmful to health. For example, it can be chips, imported low-quality chocolate, soda, fast-food, cooked with reusable vegetable oil. The second variant of the penetration of carcinogens into our bodies is obtaining them at the appropriate manufacturing plants, that is, working in chemical plants.
- Psychological causes of cancer. Previously, these reasons were not taken into account. But recently, doctors are actively talking about the fact that one of the causes of cancer can be chronic stress. It was noticed that people who were afraid and were waiting for the onset of cancer due to some life circumstances, it arose. And even if a person did not think about oncology, but was constantly in a state of stress, the risk of developing cancer was greatly increased.
- Hereditary predisposition. Well, finally, if the parents or close relatives in several generations have been documented cases of cancer, then in subsequent generations in this genus, the risk of cancer
diseases sharply increases. This does not mean that the daughter will necessarily get cancer, if her mother was ill, maybe her misfortune will go away. But to know that she is at risk and take appropriate precautions she should.
Of course, this is not a complete list of reasons for the formation of cancer, only the most studied to date are listed here. But medicine does not stand still, there is already evidence that, for example, cervical cancer is caused by a virus. And even vaccinations are already made from him. So, you see, after a few years with cancer and generally will learn to fight.
