Signs and symptoms of breast cancer

It’s important that any breast changes are investigated by your doctor as soon as possible.

We encourage all women to be aware of the normal look and feel of their breasts. Breast changes can happen for many reasons. Please contact your doctor first if you notice any breast changes that concern you, even if you’re having regular breast screens on time. This will help make sure you get the most appropriate care as soon as possible.

Some changes may be a sign of breast cancer, so it’s important to see your doctor as soon as possible if you notice:

  • a new lump or lumpiness, especially if it’s only in one breast
  • a change in the size or shape or your breast
  • a change to the nipple such as crusting or redness, or the nipple is pulled in
  • nipple discharge (liquid comes out of the nipple) that occurs without squeezing the nipple
  • a change in the skin of your breast, such as redness, puckering (pulling in) or dimpling (like orange peel)
  • an unusual pain that doesn’t go away.

Self-examinations should not replace regular breast screening.
