What should you know about juvenile fibroadenoma pathology?

A juvenile fibroadenoma is a non-cancerous breast lump that can grow during adolescence or other periods of hormonal change. Pathology assesses the tissue pattern, the supporting connective tissue, and whether the features fit a fibroadenoma. The report may use terms such as benign, cellular, or juvenile to describe the appearance; your clinician should explain which wording applies to you.

Imaging and examination may suggest a fibroadenoma, but a tissue sample provides a different kind of information. A breast ultrasound can help describe a lump and guide the next step. A biopsy may be recommended when the diagnosis is uncertain or the lump changes.

Ask for a copy of the report and have the clinician translate unfamiliar terms into plain language. Check whether the lump needs observation, repeat imaging, or removal, and ask how soreness or a scar should be managed. If removal is recommended because the lump is large, growing, uncomfortable, or affecting the breast shape, discuss [Breast Lump Excision](/treatments/breast-care/breast-lump-excision/). Relevant tests include [Breast Biopsy](/treatments/diagnostics-and-imaging/breast-biopsy/) and [Breast Ultrasound](/treatments/diagnostics-and-imaging/breast-ultrasound/).

Arrange review if a lump grows quickly, becomes fixed or unusually hard, causes skin or nipple changes, produces bloody discharge, or is accompanied by persistent pain. After a biopsy or operation, seek prompt advice for increasing redness, swelling, wound discharge, fever, or bleeding that does not settle. These changes do not establish cancer, but they deserve assessment.

Ask what the diagnosis means in your report, whether the sample was adequate, whether another area needs imaging, how growth will be monitored, and what findings would lead to excision or another biopsy.
