The risk of breast cancer in the first-degree family is 2-3 times higher than that in the normal population. Breast cancer has obvious hereditary tendency, and many breast cancer patients show the phenomenon of family aggregation. Women with a family history of breast cancer should pay attention to breast self-examination, or regular review of breast ultrasound.
2. Breast DiseasesThe risk of breast cancer in patients with breast diseases such as lobular hyperplasia and fibroadenoma is two times higher than that of the normal population. For patients with long-term breast diseases, they need to be treated actively and reasonably and followed up regularly.
3. MenstruationThe risk of breast cancer in those whose first menstruation is earlier than 13 years old is 2.2 times that of those whose age is older than 17 years old, and the risk of those whose menopausal age is older than 55 years old is greatly increased; the risk of those who have not given birth is higher than those who have given birth, and the risk of those who have given birth late is higher than those who have given birth early (with the age of 35 years old as the boundary) In addition, not breastfeeding increases the risk of breast cancer, and breastfeeding, on the contrary, can reduce the risk of breast cancer!
4. Drug factorsBreast cancer is a hormone-dependent malignant tumor. Long-term oral contraceptive pills instead of contraception during puberty, postmenopausal year-round estrogen supplementation for menopausal syndrome may increase the risk of breast cancer.
5. Dietary factorsHigh-fat diet and long-term alcohol consumption can increase the risk of breast cancer. Because the fat diet can change the endocrine environment, will enhance or prolong the estrogen stimulation of breast cells, and thus increase the risk of breast cancer.
6. Emotional factorsAlthough there is a lack of data to support this point, but reviewing many breast cancer cases do have this factor, many patients had a serious impact on the mood of the incident occurred before the onset of the disease, a negative state of mind, the lack of psychosocial support.
