Fibroadenoma
Overview
A fibroadenoma is a solid lump that forms in the breast when tissue grows over a milk-producing area.
These lumps are not cancer and don't increase your risk of getting breast cancer.
It's common to have more than one.
Causes
These happen because some breast tissue is extra sensitive to the female hormone estrogen.
They often develop during teenage years and are most common in young women, but can happen at any age.
Signs & Symptoms
You might notice a lump that:
- Feels rubbery
- Is smooth when touched
- Moves easily under the skin (sometimes called a "breast mouse")
- Usually doesn't hurt but might be tender
Size:
- Most are 1-3cm across
- Some can grow larger than 5cm
- Might get bigger during pregnancy and breastfeeding
Prevention
- Regular breast self-examination
- Maintain healthy hormone levels
- Get regular breast check-ups
Detection & Treatment
Your doctor will check through:
- Breast examination
- Mammogram or ultrasound scan
- Taking a small sample of cells
- Sometimes a larger tissue sample
Treatment:
- Most don't need treatment
- Might need surgery if larger than 3cm
- Minor operation under general anesthetic
- Some small ones can be removed through a tiny cut
Care Management
Follow-up care:
- Regular check-ups usually aren't needed unless the lump grows or becomes painful
- Having fibroadenomas doesn't increase your cancer risk
- Keep checking your breasts regularly
- Tell your doctor about any changes
