Fibroadenomas are solid breast lumps or masses that usually are:
- Round with distinct borders
- Easily moved
- Firm or rubbery
A fibroadenoma may feel like a marble within your breast when you press on it. You can have one or many fibroadenomas. Fibroadenomas range in size from being too small to be felt — detected only by mammogram or ultrasound — to 3 inches (8 centimeters) or more in diameter.
When to see a doctor
In healthy women, normal breast tissue often feels lumpy. If you detect a new breast lump or a change in your breasts — or if a breast lump you've had checked before seems to have grown or otherwise changed — make an appointment with your doctor.
