Female Breast Cancer Screening

The purpose of breast screening is to find cancer at an early stage when it is easier to treat. Screening is not a diagnostic test, but rather is designed to find cancer at an early stage among healthy people that are not showing signs of the disease. Breast cancer screening with mammography is recommended every 2 years for average-risk women aged 50 to 74. Breast cancer screening with mammography and breast MRI is recommended every year for women aged 30 to 69 who are identified as being at high risk for breast cancer.

In 2020, more than 61,500 eligible females between 50 and 74 years of age in Simcoe Muskoka received a screening mammogram with-in a 30-month period.
