Early Detection of Breast Cancer
The chance of a woman up to age 85 developing breast cancer is one in eight.
Approximately 17,000 women are diagnosed with breast cancer every year in Australia. When breast cancer is detected early, women have a much greater chance of being treated successfully and for most women the cancer will not come back after treatment.
What is a screening mammogram?
Mammograms are low dose x-rays of a woman's breasts. Screening mammograms are performed on women without any symptoms of breast cancer.
Mammograms may find a breast cancer which is too small to feel.
Who should have a regular screening mammogram?
The biggest risk factors for developing breast cancer are being a woman and getting older. BreastScreen Australia targets women aged 50 to 74, as 75% of all breast cancers occur in women over the age of 50.
- Screening mammograms are often less reliable for women under 40 years of age. The density of breast tissue in younger women often makes it difficult to detect cancers on mammograms.
- All women aged 40 to 49 years who have no breast symptoms also have free access to the BreastScreen Australia program should they choose to a have a screening mammogram.
- All women aged 50 to 74 years are encouraged to have a free mammogram every two years through BreastScreen Australia.
- Women aged 75 and over who have no breast symptoms also have free access to the BreastScreen Australia program. They should discuss whether to have a mammogram with their doctor.
Where can I have a screening mammogram?
There are currently more than 500 free screening locations including mobile screening units covering rural and remote areas across Australia.

What if I have a family history of breast cancer?
Breast cancer is a common disease in Australian women. By chance some women will have a relative who has had breast cancer, however less than 5% of all breast cancers are associated with a family history. If you are concerned about your risk, speak to your doctor.
