What should you know about B2 fibroadenoma?

The B2 label is generally used in breast pathology to indicate benign tissue. A fibroadenoma is a non-cancerous lump made from glandular and supporting breast tissue.

Fibroadenomas often feel smooth, firm and mobile, although touch alone cannot confirm the diagnosis. The clinician interprets the tissue result alongside the examination and breast imaging.

If the pathology, scan and examination agree, monitoring may be suitable. If they do not match, the team may recommend another sample or removal so the area can be assessed more fully.

Keep the breast-clinic follow-up and ask whether the result is concordant, meaning that the tissue finding explains what was seen on imaging. Follow the proposed schedule for examination or imaging rather than checking the lump repeatedly.

Treatment is not always needed. Removal may be discussed when a lump is enlarging, uncomfortable, distorting the breast, causing persistent worry, or when the findings are uncertain. The choice should reflect the expected benefit, the scar and possible changes to breast shape.

Arrange a prompt breast review if the lump grows, becomes fixed or noticeably different, or if you develop skin dimpling, nipple inversion, bloody nipple discharge, persistent one-sided pain, or a new underarm lump. These changes need assessment even after a benign result.

Seek urgent help for a breast that becomes rapidly red, hot and swollen with fever or marked illness, as this pattern can indicate an infection requiring timely treatment.

Ask whether the pathology matches the ultrasound or other imaging, whether surveillance is appropriate, and which specific change should bring you back sooner.

If surgery is offered, ask how the lump will be located, where the scar may sit, whether breast shape could change and when the final tissue result will be explained.
