Breast hyperplasia generally is not problematic, typically presenting as cyclical breast pain and swelling that appears before menstruation and may disappear afterwards. Mild cases often go unnoticed by patients, but severe cases can impact daily life and work. Some patients do not show obvious cyclical changes; instead, they may experience unilateral breast pain, swelling, or stabbing pain, which can extend to the shoulders, upper limbs, or back. A few patients might experience nipple discharge, such as yellow, brown, serous, or bloody discharge.
