What are the causes of breast cancer

So far, the incidence of breast cancer has remained high, which seriously threatens the health of our family life. Therefore, we need to find the cause of breast cancer and then treat it in a targeted manner. Only in this way can our life and health be protected. Let's take a look at the causes of breast cancer.

1. Hormone secretion disorder: The so-called hormone secretion disorder mainly refers to the secretion disorder of estrogen. Because the high-risk age of breast cancer is women aged 40 to 60. This age group is the period when women's estrogen secretion is disordered and the estrogen level is high. Due to the increase in estrogen secretion in the body, this can cause excessive proliferation of breast duct epithelial cells and cause cancer.

2. Childbirth and breastfeeding: In recent years, a large number of surveys have shown that women who have not given birth or have given birth but rarely breastfeed are more likely to develop breast cancer than women who breastfeed multiple times or for a long time. This shows that having more children and breastfeeding may increase the chance of developing breast cancer.

3. Fibrocystic breast disease: This disease has been mentioned before. It is a precancerous lesion that can easily turn into breast cancer.

4. Genetic factors: mainly manifested in a family history of breast cancer. According to foreign data, a positive family history can be manifested in two forms: one is that if the mother has breast cancer, her daughter is also prone to breast cancer. This type of breast cancer often occurs before menopause and is often bilateral; the other is that the mother has never had breast cancer, but in a family, at least two sisters have breast cancer. The incidence of breast cancer in this family is 2 to 3 times higher than that in a family without a family history, and this type of breast cancer often occurs after menopause and is often unilateral.
