What is the cause of pain in the front nipples of my aunt?

Before menstruation, if you show a breast pain or nipple pain, it is generally relatively normal. Because our women's hormone levels are constantly changing during the menstrual cycle, at the same time, the breast will get some corresponding hyperplasia before menstruation, and even show some increase in blood supply caused by breast pain or nipple pain, but after menstruation or to ovulation, it will return to normal. Under normal circumstances, younger women do not need corresponding treatment. If perimenopause women, need to go to the hospital to do a corresponding examination, such as breast ultrasound or molybdenum target examination, to determine whether there are more serious lesions inside the breast, if some corresponding conditions are shown, we need symptomatic treatment.
