Breast rubbing does not prevent mastopexy. Mastopexy is not a disease, but a pathological term that belongs to a series of problems, including physiological and pathological hyperplasia. The physiological stage includes breast development during puberty, the proliferation stage of the breast after ovulation in the menstrual cycle, and the physiological changes in the breast during pregnancy and lactation are all physiological processes, not diseases. Pathological mammary hyperplasia also includes a variety of situations, some of which are prone to cancer and some are not. If you blindly rub your breasts and do not know which type of mammary hyperplasia they belong to, it is easy to stimulate this part of the mammary hyperplasia that is prone to cancer to lead to rich blood flow and promote the risk of lesion expansion, cancer and even metastasis, so rubbing your breasts not only can not prevent mammary hyperplasia, but may also lead to adverse consequences.
