Fibroadenoma

What it is

A fibroadenoma is a solid, benign breast lump made of normal breast gland and connective tissue. It is not harmful and is a very common type of breast finding. Think of it as a harmless overgrowth of tissue that grew in an organized way.

How common it is

These are the most common type of benign breast lump, especially for women in their 20s and 30s. However, they can appear at any age.

What you may notice

You may feel a single lump that is firm, smooth, and round, a bit like a small marble. It usually does not cause pain and moves easily under your fingers when you press on it.

What can contribute

Fibroadenomas seem to be related to your body's hormones, like estrogen. This is likely why they are more common during your reproductive years and may change in size with pregnancy or your period.

How it is usually checked

Your provider will likely do a physical exam of your breast. They may also suggest imaging, like a breast ultrasound or a mammogram, to get a closer look. Sometimes, a small sample, called a biopsy, is taken to confirm what it is.

Does this change my long-term risk?

Having a simple fibroadenoma does not change your long-term breast health risk.

Comfort and everyday care

• Some women find that reducing caffeine in their diet helps with overall breast tenderness.
• Wearing a comfortable and supportive bra can help ease any discomfort.
• Applying a warm compress to the area may feel soothing if the lump is tender.
