What factors are the incidence of breast cancer related to? The incidence of breast cancer is related to genetic factors, reproductive factors, hormone levels, lifestyles, dietary habits and environmental factors. These include family history, genetic mutation, early onset, menopause, unborn or late childbearing, long-term hormonal substitution therapy, fat diet, obesity, lack of exercise, drinking, etc. Early menstruation in January, aged 50-55 or >42; late marriage, late childbearing. 2 The age at which the first child is born is too late, without breastfeeding or after the age of 35. 3 Internal source factor, high estrogen level per se. Exogenous estrogen, substance abuse, menopausal and post-menopausal long-term hormone substitution treatment. 4 has a family history of breast cancer. Family history refers to breast cancer among first-degree relatives (parents, siblings, children). The other side of the breast cancer patient. Six patients with a history of chest therapy. 7 There is a history of benign breast diseases, such as abnormal increase in the upper skin of the heavy mammography catheter, blood spills from the nipple, fluid spills, etc. Overweight, chronic high-fat diet, and alcohol. Mental factors, chronic anxiety, depression. Women who are accustomed to staying up late, working at night and smoking on a permanent basis. The causes of breast cancer are not yet known, and to date scientists have not identified the exact causes of breast cancer, but many high-risk factors associated with breast cancer have been identified. As high-risk factors for breast cancer accumulate, their risk of disease increases. Causes of morbidity: Breast is the target organ for various endocrine hormones, in which female ketone and female diol are directly related to breast cancer. Exposure to estrogen in the body can be increased or prolonged by early menstruation age (55 years), infertility and late first birth age (>30 years), short breastfeeding time and post-menopausal estrogen substitution therapy, which is closely related to breast cancer. In addition, genetic factors are a high risk factor for breast cancer. Breast cancer has a history among first-degree relatives (e.g. parents, children and siblings) and is two to three times higher than in the general population. Some genetic mutations also increase the risk of breast cancer. In addition, certain physical factors, such as breast radiation treatment during childhood, are also contributing factors to breast cancer. Inducing factors: In addition to the above-mentioned high-risk factors, there are still some lifestyles that are associated with the incidence of breast cancer, such as overnutrition, obesity, high-fat diets and overdrinking, which can increase the incidence of breast cancer.
