summary

Cancer is also a malignant tumor. There are many causes of cancer, including physical and chemical carcinogens, viral carcinogens, such as hepatitis B virus, ionizing radiation and other carcinogens. The usual living habits are also closely related to the occurrence of cancer. A friend of mine is due to excessive smoking, causing lung cancer. The common ones are alcohol and diet In addition, cancer is related to heredity, and cancer can also be caused by tumors in the transplanted organs. Let's talk about what causes cancer.

What causes cancer

Reason 1: the cause of cancer is also related to the body's own resistance. When people's anti-cancer ability is weakened, they can't normally limit the proliferation of cancer cells. The causes of cancer also include unhealthy sex life, such as AIDS. The causes of different cancers are different.

The second reason: when the regulatory mechanism of normal cells is damaged and destroyed, it will lead to cancer. Secondly, cancer is closely related to the age and living habits of patients, and its own genes are also closely related. If the oncogene is relatively active, it is more likely to get cancer when exposed to carcinogens.

Reason 3: the cause of cancer is very complicated. The mental aspect is also related to cancer. Especially for people who have been in a state of mental depression and mental tension for a long time, chronic stimulation of the immune system and neuroendocrine system will gradually reduce the body's immunity, thus increasing the incidence of cancer.

matters needing attention

In order to prevent cancer, we should keep a happy mood, calm and optimistic attitude, actively participate in sports, stay away from carcinogens, eat less fried and carcinogenic food, and eat more anti-cancer food.
