Symptoms
By Mayo Clinic staff
Fibroadenomas are solid breast lumps or masses that usually are:
- Round with distinct borders
- Easily moved
- Firm or rubbery
- Painless
A fibroadenoma may feel like a marble within your breast when you press on it. You can have one or many fibroadenomas. They usually grow to about 1 to 2 centimeters (cm) in size, but they can become even larger. A fibroadenoma that measures 5 cm or greater is referred to as a giant fibroadenoma.
When to see a doctor
Normal breast tissue in healthy women often feels lumpy or nodular. If you detect the presence of any new breast lumps, however, or if a previously evaluated breast lump seems to have grown or otherwise changed, make an appointment with your doctor to get it checked out.
