What is the main cause of breast cancer?

Breast cancer is a common breast tumor. Many women suffer from breast cancer in middle age. So, what are the main causes of breast cancer ? Let's learn more about this from the following article.

1. Too many abortions: Normal spontaneous abortions do not increase the risk of breast cancer. However, repeated artificial abortions or multiple artificial abortions before the age of 18 are prone to breast cancer. Therefore, this is one of the causes of breast cancer.

2. Family inheritance: This may also be the cause of breast cancer. A family history of hereditary breast cancer can be manifested in two forms: one is that the mother has breast cancer and the daughter also develops breast cancer, the onset age is young, often occurs before menopause, and is mostly a cause of bilateral breast cancer; 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 2-3 times higher than that in a family without a family history, and is often unilateral.

3. Menstrual factors: Women who have their first menstruation before the age of 12 have a 2.2 times higher risk of breast cancer than those who have their first menstruation at the age of 17; women who have their menopause after the age of 50 have a 1-fold higher risk of breast cancer than those who have their menopause after the age of 45. This is also a cause of breast cancer.

The above factors are the causes of breast cancer. I hope you can understand how breast cancer occurs. If you have other questions about breast cancer, you can contact our online experts to answer them.
