8 risk factors for breast cancer

　　Women should love themselves and refuse breast cancer ,persist in healthy . At present, the cause of breast cancer is not completely clear, but it is worth noting that scientists have summarized eight major risk factors for breast cancer:

　　family inheritance

　　Family history of hereditary breast cancer can manifest in two forms: one is that the mother suffers from breast cancer, and the daughter is also prone to breast cancer. The age of onset is young and often occurs in amenorrhea anterior, mostly bilateral； Another type 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 families with no family history. This kind of breast cancer mostly occurs after amenorrhea and is often unilateral.

　　menstrual factors

　　If the age of menarche is earlier than 12 years old, the risk of breast cancer is 2.2 times greater than that of those who have menarche at 17 years old.； menopause People who go through menopause after the age of 50 are about twice as likely to develop breast cancer than those who go through menopause after the age of 45.

　　Too many miscarriages

　　Normal spontaneous abortion does not increase the risk of breast cancer, but repeated artificial abortions, or those who have had multiple artificial abortions before the age of 18, are prone to breast cancer. disease , increasing the risk of breast cancer. Reminder: multiple times flow of people Easy to cause cervical cancer

　　Artificial feeding

　　Breastfeeding is one of the best natural ways to prevent breast cancer. Breastfeeding can reduce the risk of breast cancer by 20% to 30%.

　　Recommendation: The longer you breastfeed, the smaller the risk of breast cancer.

　　Poor quality of sexual life

　　Breast disease and sexual life are closely related. female Sexual repression can increase the incidence of breast lobular hyperplasia and breast tumors. Relevant domestic surveys show that 86% of women with breast lobular hyperplasia have never reached orgasm during sex. ； The older the age at first marriage, the higher the incidence of breast cancer.

　　depressed mood

　　Single women, left-behind women, public relations girls, retired female workers and some middle school teachers are more likely to suffer from breast diseases, and the incidence rate of breast cancer is also high. Because these women are prone to stress and anxiety, loneliness and depression, sadness, depression, irritability and other depressive emotions, they are often stimulated by negative emotions for a long time and the body's life rhythms are disrupted. nerve The dysfunction of the endocrine system leads to an imbalance in the internal environment and decreased immunity, which can reduce the production and release of thymosin by the thymus. The ability of lymphocytes and macrophages to monitor and phagocytose mutated cells in the body decreases, making cancer prone to occur.
