Breast screening detection rates
Each year BreastScreen WA performs over 100,000 screening mammograms for Western Australian women.
Screening mammograms can detect up to 90 per cent of breast cancers.
About 950 of every 1,000 women screened will have no abnormality detected. These women will be sent a letter within 2 weeks to let them know their mammogram was normal.
Some women may be recalled for further tests, but this does not necessarily mean breast cancer has been detected.
About 50 women out of 1,000 will be called back for further tests. About 6 of these women may have a breast cancer detected.

For all women, there is a chance that:
- the screening mammogram will miss a change due to breast cancer (a false negative result)
- further tests will be performed to examine a change that is not due to breast cancer (a false positive result).
