How does breast cancer develop? The age of onset of breast cancer in our country is mainly concentrated in the 40-45-year-old, foreign women 45 to 50 years old is the first peak, after which it gradually declines, to the age of 60 is the second highest peak. In fact, the true cause of breast cancer has not yet been fully understood, but the incidence of breast cancer has a certain relationship with estrogen and progesterone (such as menarche and menopause age, reproductive status, birth control pills, etc.), and some breast cancer and family genetic Relationships, in addition to diet, obesity and other factors may also lead to morbidity. Let’s talk about genetics first. First-degree relatives (mothers, sisters, etc.) found breast cancer, then the family is at high risk, but high-risk does not equal to hereditary: If the mother has breast cancer after menopause, her daughter has a better chance of developing breast cancer than normal people. 20%; If the mother is pre-menopausal, her daughter has twice the chance of developing the disease. If the mother has breast cancer unilaterally, the daughter has twice the chance to develop the disease. However, if the mother is pre-menopausal, it is also bilateral breast cancer. 7 to 8 times more opportunities. Breast cancer is associated with reproductive or endocrine factors, and the following population has a 1.3 to 3 times the chance of developing a normal person. 1. Menarche age less than 12 years or menopause older than 55 years. 2. The first child's reproductive age is more than 35 years old, or she has not had childbirth and has not breast-feeding after delivery. 3. The menstrual cycle is short, indicating that estrogen has a long duration of action. 4, high levels of estrogen after menopause or the use of estrogen replacement therapy. Lobular hyperplasia is a common condition in women. It often manifests as premenstrual breast tenderness and improvement after menstruation. This is a physiological change and generally does not require treatment. If lobular hyperplasia develops further and there is epithelial dysplasia, then we call it "precancerous lesion," but this is very rare. Some breasts have cysts, duct dilatation, mastitis, nipple discharge, etc., which are not proliferative lesions, and do not have much to do with the occurrence of breast cancer.
