Breast cancer is the most common cancer affecting women

In 2020, it is estimated that 19,974 Australians will be diagnosed with breast cancer, and it’s estimated that breast cancer will account for 14% of all new cancer cases diagnosed in 2020. However it is important to remember that most women survive breast cancer.

Breast cancer in men is rare with the latest statistics recording 164 Australian men diagnosed in 2019.

Australian statistics

  • In 2021, it is estimated that the risk of a woman being diagnosed with breast cancer by their 85th birthday will be 1 in 7, while 19,866 Australian women will be diagnosed. This will make it the most commonly diagnosed cancer among Australians.In 2021, it is likely that it will remain the fifth-most common cause of death from cancer and the second-most common cause of death from cancer among females.
  • Breast cancer is the most common cancer diagnosed in women, including Aboriginal and Torres Strait Islander women. Only around 5-10% of breast cancers are due to a strong family history.
  • More than half of all breast cancers in Australia are discovered by the woman herself or her own doctor. The early detection of breast cancer can increase the chance of successful treatment.
  • Nine out of 10 breast changes are not due to cancer, but you should see your doctor to be sure.
  • The chance of surviving for at least five years after being diagnosed is about 91%.
  • Breast cancer is also diagnosed in men (although the chances of this occurring are much lower than for women). About 167 men in Australia this year are estimated to be diagnosed with breast cancer.Source: Cancer Australia 2019

FAQs

Breast cancer can start in different parts of the breast, most commonly in the ducts or the lobules. Breast cancer develops when cells in these areas change and begin to grow and multiply in an uncontrolled way.

Unfortunately, we don’t know. There is always research taking place, but there isn’t an agreed, single cause of breast cancer. However, research has shown that there are multiple factors that increase the risk of developing breast cancer.

There are many different things that can indicate breast cancer, but it’s important to know that most breast changes aren’t due to breast cancer. This said, you should absolutely see your doctor as soon as possible if you notice any of the changes below, or if you feel concerned about your breast health.

  • A lump, lumpiness, or thickening in the breast or armpit – especially if it’s only in one breast
  • A change in size or shape of your breast
  • Changes to your skin like redness, dimpling, or puckering
  • Discharge from your nipple, or if your nipples invert
  • A change to your nipple like a rash, an ulcer, or even itchiness
  • Pain that is persistent, or unusual

The process might be different from one person to another, but remember also that most changes are not due to breast cancer. You might however need the following tests to confirm what you feel:

  • A clinical breast exam by your doctor
  • A mammogram and/or an ultrasound
  • A fine needle biopsy or core biopsy
