Overview
Multiple fibroadenoma of the breast is a condition where a person develops several benign (non-cancerous) lumps in one or both breasts. These lumps are called fibroadenomas, which are made up of both glandular tissue (the tissue that makes milk) and fibrous connective tissue. When someone has more than one of these lumps — sometimes called 'multiple fibroadenomas' or 'fibroadenomatosis' — it falls under this diagnosis. It is worth noting that this condition is listed as 'obsolete' in some medical databases, meaning it may now be classified differently or grouped under broader breast disease categories. Fibroadenomas are most commonly found in younger women, typically in their teens, twenties, and thirties. They usually feel like smooth, rubbery, movable lumps under the skin. Most are painless, though some women notice tenderness, especially around their menstrual cycle. Having multiple fibroadenomas can cause anxiety, discomfort, and concern about breast cancer risk. Treatment depends on the size, number, and symptoms of the lumps. Many fibroadenomas are simply monitored over time with regular ultrasound or clinical exams. Some may shrink or disappear on their own. If lumps grow, cause pain, or raise concern, they can be removed surgically or treated with minimally invasive procedures. The overall outlook is generally very good, as these lumps are benign.
