Why do breasts become swollen and painful before menstruation?

Patient's question:

No

Doctor's answer:

Your condition is considered to be related to breast hyperplasia. Breast hyperplasia refers to the proliferation of breast epithelial and fibrous tissues, as well as degenerative structural changes in breast ducts and lobules, along with progressive growth of connective tissues. The main cause of its onset is primarily due to endocrine hormones.
