How does breast duct cancer cause?

First: family history of breast cancer, breast cancer has obvious genetic tendency, breast Research Association survey found that women with family history of breast cancer, the risk of breast cancer is 2 ~ 3 times higher than ordinary people. Generally, the risk of breast cancer among first-degree relatives (mothers, daughters, sisters) or second-degree relatives (grandmothers, grandmothers, aunts, etc.) is twice that of the general population. If there are more than three first-degree relatives with breast cancer, the risk will be as high as four times that of normal people.

Second: with a history of benign breast diseases, researchers from the American Cancer Research Center found that patients with benign breast diseases have a higher risk of breast cancer than those who have never had benign breast diseases. The risk of breast cancer is 1.5-2 times higher than that of non proliferative diseases. Patients with breast fibroadenoma and fibrocystic disease have 2-3 times higher risk of breast cancer. Patients with atypical lobular hyperplasia and atypical ductal hyperplasia have a 3.5-6-fold risk of breast cancer.

Third: the age of first birth is later than 35. According to a social survey by the Japanese women's Research Association, women who give birth later than 35 have twice the risk of breast cancer as women who give birth earlier than 20. In addition, breast-feeding can reduce the risk of breast cancer. The survey found that breast-feeding per year can reduce the risk of breast cancer by 4.3%.

matters needing attention

(1) early treatment of benign breast diseases, such as atypical hyperplasia, papilloma, sclerosing adenosis, and other benign diseases, is related to the incidence rate of breast cancer. Therefore, once these diseases are found, they should be treated as soon as possible（ 2) Prolonging the time of breast-feeding or increasing the number of births, insisting on breast-feeding, prolonging the time of breast-feeding, or having more babies can reduce the risk of breast cancer（ 3) Changing bad habits, long-term use of estrogen drugs, long-term drinkers or long-term repeated X-ray radiation will increase the risk of breast cancer. Therefore, the use of other drugs instead of estrogen drugs, B ultrasound, physical red light instead of X-ray examination, abstinence, reduce the risk of breast cancer.
