What are the main predisposing factors of common breast cancer?

What are the common risk factors for breast cancer? I believe many people have this question. Breast cancer is a malignant tumor that is more common in female friends. Since the cause of breast cancer has not been fully clarified, we only need to pay more attention to the details of life and the risk factors in our daily life. Let us learn about the risk factors 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 for 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. This is one of the factors that induce breast 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. It is also a risk factor for breast cancer.

4. Genetic factors: mainly manifested in a family history of breast cancer, which is also one of the predisposing factors 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.
