Breast cancer symptoms
Some people have no symptoms and the cancer is found during a mammogram (a low-dose x-ray of the breast) through the National Breast Cancer Screening Program.
If you do have symptoms, they could include:
- a lump, lumpiness or thickening, especially if it is in only one breast
- a change in the size or shape of the breast
- a change to the nipple, such as a change in shape, crusting, sores or ulcers, redness, a clear or bloody discharge, or a nipple that turns in (inverted) when it used to stick out
- a change in the skin of the breast, such as dimpling or indentation, a rash, a scaly appearance, unusual redness or other colour changes
- swelling or discomfort in the armpit
- ongoing, unusual pain that is not related to your normal monthly menstrual cycle, remains after your period and occurs in one breast only.
Most breast changes aren’t caused by cancer. If you have symptoms, see your doctor without delay.
