Why is breast cancer a rich disease? As a woman, how to prevent breast cancer?

What is the main cause of breast cancer?

(1) Family history of breast cancer

Studies have shown that 5% to 10% of breast cancer is familial aggregation. If a close relative has breast cancer, the risk will increase by 1.5 to 3 times; If two close relatives have breast cancer, the prevalence rate will increase seven times. The younger the onset age, the higher the risk of breast cancer in close relatives.

(2) Dietary factors

At present, it has been proved that pickled meat products, pickles, spoiled vegetables and meat all contain nitrite. Nitrite itself does not cause cancer, but in cooking or other cases, nitrosamines, a primary carcinogen, will eventually be produced. In addition, research shows that high-calorie and high-fat diet can promote the synthesis of endogenous fat, which leads to obesity. The incidence of breast cancer in obese people is three times that of normal weight people.

In animal research experiments, it has been proved that hormones such as estrogen and prolactin can cause cancer. Studies have shown that women before and after menopause, as well as women with early menarche and late menopause, are more likely to suffer from breast cancer.

Environmental factors are also important factors leading to breast cancer, such as frequent contact with some radioactive substances or chemicals, which are closely related to the incidence of breast cancer. At the same time, bad habits and lifestyles, such as staying up late, smoking and drinking, are closely related to breast cancer.

If you are in a state of anxiety, impatience or depression for a long time, women's body rhythm is more prone to disorder, endocrine is easy to be unbalanced, and even the body's metabolism will be unbalanced, and the body's immune ability will decline. In severe cases, it may even directly induce breast cancer.
