Breast hyperplasia usually manifests as cyclical symptoms such as swelling, pain, and tenderness that often occur or worsen before menstruation and may decrease or disappear after menstruation. Minor cases might not be a concern for patients, but severe cases can affect daily life and work. Symptoms might include pain in one or both breasts, which can extend to the shoulders, upper limbs, or shoulder blades. Additionally, a small number of people might experience nipple discharge, which could be milky, clear, yellow-green, or brown in color.
