If you feel a lump in your breast, always get it checked by a GP. Most breast lumps are harmless, but some can be serious.
See a GP if you notice:
- a lump in your breast or armpit
- any other unusual changes in your breasts – such as the nipple turning inwards, dimpled skin or bloodstained nipple discharge
Changes in the breasts can be a sign of breast cancer. This is easier to treat if it's found early.
If you have a breast lump, a GP will look at and examine your breasts.
If they're not sure what's causing the lump, they'll refer you to a hospital or breast clinic for further tests.
These tests usually show that a lump is not cancer.
What happens at the breast clinic
At the hospital or breast clinic, you may have a:
- breast examination
- scan – usually a breast X-ray (mammogram) or ultrasound
- biopsy – where a needle is inserted into the lump to remove some cells for testing
These tests are often done during the same visit. You'll usually be told the results on the same day, although biopsy results take longer – you may have to wait about a week.
Treatment for a breast lump depends on the cause. Most are harmless and may go away on their own without treatment.

Lumps in the breasts can have lots of different causes.
They're often caused by something harmless like a non-cancerous tissue growth (fibroadenoma) or a build-up of fluid (breast cyst).
Sometimes, a breast lump can be a sign of something serious like breast cancer.
Do not try to self-diagnose the cause of your lump – always see a GP.
