What it is
It is usually harmless but can be upsetting or tender.
Treatment depends on the cause, such as changing a medicine. Surgery is sometimes an option if it does not go away.
Common signs
- Swelling of breast tissue under the nipple
- Tenderness
- One or both sides affected
How it is usually diagnosed
- Examination
- Blood tests for hormones and other causes
- Ultrasound or mammogram, sometimes
Records worth keeping
Keeping these together makes each appointment easier, especially when you see a new doctor:
- Hormone blood test results
- Imaging reports
- A list of medicines
- Specialist letters
Questions to ask your doctor
- What is causing it?
- Could one of my medicines be responsible?
- Will it go away on its own?
When to get help right away
Call 112 or go to the nearest emergency department if you have:
- A hard lump, nipple discharge or bleeding, or skin changes on the breast: get it checked soon
