What should you know about small fibroadenoma?

A small fibroadenoma is usually a benign solid breast lump, but assessment confirms its features and guides follow-up. It may feel smooth, firm, and mobile under the skin. Fibroadenomas can change with hormonal shifts and may be noticed during a self-check or examination. A familiar diagnosis should not be assumed for a new or changing lump.

Fibroadenomas are made from glandular and supporting breast tissue. Many remain stable, while some grow or become more noticeable. Breast ultrasound can show whether a lump has the appearance expected of a fibroadenoma. Depending on its appearance, age, symptoms, and change over time, a clinician may recommend observation or a breast biopsy. A scan cannot replace a clinical review when the lump changes.

Book an appointment for a new lump, even if it is small and painless. Note when you first felt it, whether it changes during the menstrual cycle, and whether there is nipple discharge or skin change. Take any previous imaging to the appointment. If the lump is uncomfortable, discuss whether monitoring, repeat imaging, biopsy, or breast lump excision best fits your situation.

Seek prompt medical review for a lump that grows, becomes fixed, causes skin dimpling, pulls the nipple inward, or is accompanied by bloody discharge or enlarged underarm nodes. Urgent assessment is appropriate for rapid breast swelling with redness, warmth, fever, or severe pain. These signs do not establish a diagnosis, but they should not wait for routine monitoring.

Ask what the imaging shows, whether a biopsy is needed, how the lump will be monitored, and which change should prompt an earlier visit. If removal is discussed, ask about the reason, the procedure, and what happens to the tissue afterward.
