Breast cancer signs and symptoms

Breast cancer can have several symptoms. The first noticeable symptom is usually a lump or area of thickened breast tissue.

Most breast lumps are not cancerous, but it's always best to have them checked by a doctor.

If you notice any of the following symptoms, make an appointment with your GP as soon as possible:

  • a new lump or area of thickened tissue in either breast that was not there before,
  • a change in the size or shape of one or both breasts,
  • a discharge of fluid from either of your nipples,
  • a lump or swelling in either of your armpits,
  • a change in the look or feel of your skin, such as puckering or dimpling, a rash or redness,
  • a rash (like eczema), crusting, scaly or itchy skin or redness on or around your nipple,
  • a change in the appearance of your nipple, such as becoming sunken into your breast.

No time for cancer, make time to get checked.
