Lobular fibroadenoma: what to know about a breast lump

Fibroadenomas are made of glandular and connective breast tissue. They can feel smooth, firm and mobile, although texture varies and self-examination cannot confirm the cause. Hormonal changes may make a fibroadenoma feel larger or more tender at some times. The word lobular may describe its shape or the tissue pattern seen on imaging or pathology; your report should be interpreted in context. Breast ultrasound can show whether a lump has features that fit a fibroadenoma, while a biopsy may be recommended when imaging is uncertain or the lump changes.

Arrange an examination for any new breast lump, even if it is painless or seems familiar. Bring previous imaging reports if available and note when you first noticed the lump, whether it changes with your cycle, and whether there is nipple discharge or skin change. Depending on age, examination findings and imaging, a clinician may suggest observation, repeat imaging or tissue sampling. If the lump is growing, uncomfortable, large or causing concern, breast lump excision may be discussed. Do not squeeze or repeatedly press the area.

Seek prompt assessment for a lump that grows quickly, becomes fixed, causes skin dimpling, produces bloody nipple discharge, or is associated with a newly inverted nipple or enlarged underarm nodes. Redness, warmth and severe tenderness with fever need timely review as they may reflect inflammation or infection. A breast lump is not proof of cancer, but changes should be examined rather than watched indefinitely.

What features make this lump look like a fibroadenoma? Do I need breast ultrasound or a biopsy? If we monitor it, when should it be checked again? What changes would make breast lump excision reasonable?
