Breast lumps are common and usually aren’t cancer. Other conditions that can cause them include:
- Fibroadenoma. This causes smooth, round lumps. You can move them, and they don’t hurt.
- Fibrocystic changes. You may have cysts, pain, or tenderness.
- Breast infections. Small sacs of pus (abscesses) often happen after childbirth.
- Clogged milk glands
- Injuries that form scar tissue
Talk to your doctor if you notice any kind of lump in your breast or armpit. Get medical care as soon as possible if you also have signs of an infection such as redness, swelling, or discharge. Find out more on causes and types of breast lumps.
