1, during menstruation due to the influence of various related endocrine hormones, breast tissue will undergo some physiological proliferation and recovery changes, resulting in breast tissue in different degrees of congestion, edema, however, these changes may interfere with the doctor’s examination of the tiny lumps in the breast, so we should pay great attention to it. Most experts believe that the seventh to tenth day after the onset of menstruation is the best time to check the breast, when estrogen has the least impact on the breast, and the breast is in a relatively static state, so breast lesions or abnormalities are easily detected. Older women in post-menopause have less estrogen in their bodies and their breast tissues are less affected by endocrine hormones, so they can choose the consultation time at will. If breast lesions are detected during breast self-examination or screening, you should consult a doctor early, respect the doctor’s orders for various breast examinations and follow up in a timely manner. 5, some patients in clinical remission of benign breast disease, a long time no longer do regular review, until the original benign lesions have become malignant, it will be very difficult to cure. Therefore, early consultation should be an important principle, and choosing the best time for consultation is an important means to improve the correct diagnosis rate.
