What if a fibroadenoma is getting bigger?

Fibroadenomas can respond to hormonal shifts and may become more noticeable during some stages of life or around a menstrual cycle. A lump may also seem larger when surrounding breast tissue is swollen or tender. Even when a lump was previously assessed, a clear change in size, shape, firmness, or mobility deserves a fresh review. Growth by itself does not establish a cancer diagnosis, and it should not be interpreted without an examination.

Contact a clinician and describe when the change began, whether it was gradual or sudden, and whether you have pain, discharge, or skin changes. A breast ultrasound may compare the lump's structure and appearance with an earlier assessment. Depending on the examination and imaging, a breast biopsy may be discussed. If the lump is large, uncomfortable, or continuing to change, ask whether breast lump excision is appropriate.

Seek prompt care if growth is accompanied by a lump that feels fixed, marked breast swelling, skin dimpling, nipple inversion, bloody discharge, redness, warmth, or fever. A sudden painful change may reflect inflammation or another problem that needs timely treatment. Do not wait for a routine appointment if symptoms are rapidly worsening.

Ask how the current size compares with prior measurements, whether the imaging pattern remains reassuring, and what follow-up interval is suitable. Ask what findings would lead to biopsy or removal, and how to monitor the lump without repeatedly pressing it.
