What are the causes of breast cancer?

Breast cancer is one of the most common malignant tumors in women. According to statistics, the incidence rate accounts for 7-10% of all malignant tumors in the body. Its onset is often related to genetics, and the incidence rate is higher in women between the ages of 40 and 60 and before and after menopause. Only about 1-2% of breast patients are male. It is a malignant tumor that usually occurs in the glandular epithelial tissue of the breast. It is one of the most common malignant tumors that seriously affects women's physical and mental health and even endangers their lives. Male breast cancer is rare.

(1) Genetic susceptibility: Clinical data from family history surveys show that the incidence of breast cancer in women with a family history is higher than that in women without a family history. In particular, the risk of breast cancer in women with bilateral breast cancer and those who develop the disease at a young age is 9 times that of the general population. This may be related to genetic factors, which make them susceptible to breast cancer and have internal causes of the disease.

(2) Endocrine factors: Endocrine disorders are one of the causes of breast cancer. The abnormal stimulation of endocrine hormones by the breast for a long time leads to breast canceration. Among them, estrogen and progesterone are the two endocrine hormones most closely related to breast canceration. This has been confirmed by many clinical, pathological and physiologists.

(3) Viral factors: Virus particles can be transmitted through breastfeeding and cause breast cancer. This has been confirmed by many animal experiments, so some scholars speculate that the cause of breast cancer may be viruses, but there is no sufficient epidemiological evidence and further research is needed.

(4) Other factors: Low anti-cancer immune function of the body suppresses the immune function of anti-cancer factors; and traumatic stimulation to the breast and radiation damage have all been reported to increase the risk of breast cancer.

The above is an introduction to "What are the causes of breast cancer?" People who are related to the pathogenic factors of breast cancer are advised to take preventive measures against breast cancer.
