3. Breast injury: Breast injury, such as nipple laceration, breast extrusion or impact, may lead to mastitis.
4. Immune system problems: People with low immune system function, such as diabetes, AIDS patients or people who are receiving immunosuppressive treatment, may be more likely to suffer from mastitis.
5. Breast surgery: Breast surgery, such as breast plastic surgery or breast biopsy, may increase the risk of mastitis.
6. Breast infection: Breast infection, such as breast abscess, may develop into mastitis.
7. Bad living habits: Smoking, drinking, malnutrition, lack of exercise and other bad living habits may increase the risk of mastitis.
Please note that the above factors are just some common risk factors, and the specific situation needs to be comprehensively evaluated in combination with personal health status and lifestyle.
