Fibroadenoma behind the nipple: what to know

A lump behind or close to the nipple may be felt in the area where ducts and glandular tissue meet. Fibroadenomas can be smooth and mobile, but location alone cannot confirm the diagnosis. Tenderness may vary with hormonal changes, and pressure from clothing or breastfeeding can make the area more noticeable.

A clinician will examine the nipple, areola, and surrounding breast tissue, then choose imaging suited to your age, symptoms, and examination. Ultrasound can help distinguish a solid lump from a fluid-filled area. A biopsy may be suggested when imaging does not provide enough certainty.

Do not repeatedly squeeze or press the area to test it; that can increase soreness and irritation. Note whether the lump moves, changes with your cycle, or is associated with discharge. Arrange an assessment for a new lump, even if it is not painful.

Your clinician may recommend observation with planned review, further imaging, or tissue sampling. If the lump is troublesome, enlarging, or uncertain after assessment, Breast Lump Excision may be discussed. The linked Breast Ultrasound and Breast Biopsy pages explain those options.

Seek prompt care for bloody or clear spontaneous nipple discharge, new nipple inversion, ulceration, skin dimpling, marked redness, fever, or a lump that becomes fixed or grows quickly. A painful warm breast with fever may indicate infection and needs timely attention.

Is the lump directly behind the nipple or in nearby tissue? Which imaging test is suitable? Do I need a biopsy? Could the lump affect breastfeeding? What symptoms should trigger an earlier appointment?
