How breast cancer is diagnosed

Signs and symptoms of breast cancer

Some of the signs and symptoms of breast cancer include:

  • a lump in the breast
  • a change in the size or shape of the breast
  • dimpling of the skin or thickening in the breast tissue
  • a nipple that’s turned in (inverted)
  • a rash (like eczema) on the nipple
  • discharge from the nipple
  • swelling or a lump in the armpit.

A lump in the breast is the most common symptom of breast cancer.

Most breast lumps are not cancerous. They are usually fluid-filled lumps (cysts) or a fibroadenoma, which is made up of fibrous and glandular tissue. But it is important to get a lump or any of these symptoms checked by your GP straight away.

If a lump or other symptoms is caused by breast cancer, the earlier you have treatment the more successful it is likely to be.
