Most women of childbearing age have varying degrees of breast enlargement, but the chance of breast cancer is 40-60 per 100,000, so the vast majority of breast enlargement will not turn into breast cancer. The most important thing is to have a specialist examine the breast enlargement and make a judgment whether it is normal, or is it a medium or high risk? Then get a follow-up recommendation. Most women only need regular checkups and no medication or surgery. Mammary gland hyperplasia is also associated with emotions and changes in the menstrual cycle, which are mainly self-regulated.
