Genetic factors: Some gene mutations or gene mutations (such as BRCA 1 and BRCA2 gene mutations) can increase the risk of breast cancer. If there are breast cancer cases in the family, the individual's risk of breast cancer will also increase.
Age: With the increase of age, the risk of breast cancer will also increase. Most cases of breast cancer occur in women aged 50 and over.
Estrogen exposure: Long-term exposure to estrogen will increase the risk of breast cancer. For example, factors such as early menarche, late menopause, never pregnancy or late childbearing may cause estrogen to act on breast tissue for a longer time.
High-density breast: Breast density refers to the ratio of stroma and gland to adipose tissue in breast. Women with high breast density have a higher risk of breast cancer.
Personal lifestyle: Unhealthy lifestyle may increase the risk of breast cancer, such as high-fat diet, lack of exercise, obesity, alcoholism and smoking.
Long-term estrogen replacement therapy (ERT) or oral contraceptives: Long-term use of ERT or oral contraceptives may increase the risk of breast cancer.
Radiation exposure: Long-term chest radiation therapy (such as treating other types of cancer) may increase the risk of breast cancer.
Please note that these factors are only one of the possible risk factors, and it is not possible to determine whether it will lead to breast cancer alone. Everyone's situation is unique. If you have any concerns about breast cancer, please consult a professional doctor or breast specialist for further evaluation and consultation. If necessary, you can get an electronic rehabilitation manual by private message or message.
