If there is pain and swelling in the breast after menstruation, it is clinically abnormal and most of them are caused by hyperplasia of the breast tissue, which can be diagnosed by ultrasound. If the diagnosis cannot be confirmed clinically through ultrasound, a mammogram can be done to find out if there is a local tumor in the breast, so this situation should be taken seriously. If you have breast enlargement, it is recommended to actively give treatment, and it is also recommended to keep a happy mood in daily life, to develop good habits, not to stay up late, and to avoid anxiety, which can have a complementary therapeutic effect on breast enlargement. If organic lesions occur, such as localized tumors in the breast, it is recommended to combine the clinical history with the specific situation and, if necessary, surgery to give the relevant treatment.
