Breast cancer: The facts
Breast cancer is the most common cancer diagnosed in Australian women.
- 14 560 women were diagnosed in 20121
- 12% of all cancers (men and women) 1
- Lifetime risk for a woman developing breast cancer to age 75 is 1 in 112
Breast cancer is the second leading cause of cancer deaths in Australian women:
Ductal cell carcinoma in situ (DCIS)
DCIS is a non-invasive breast cancer. The incidence of DCIS is highest in women aged 50 – 69. Women diagnosed with DCIS are four times more likely to develop invasive breast cancer.3
Early breast cancer
Early breast cancer is non-metastatic, invasive, localised breast cancer that may or may not have spread to lymph nodes in the breast or armpit.3
The 5 year survival rate for women diagnosed with early breast cancer in Australia is 97%.3
Secondary breast cancer
Secondary breast cancer is metastatic or advanced cancer. Common sites of metastases are liver, lungs, brain and bones. Around 7% of breast cancers are diagnosed at this stage and the 5 year survival is around 40%.3
