About this section
This section describes tests and modalities used in breast cancer screening within Canada, including mammography, tomosynthesis, MRI, ultrasound, and mobile screening clinics.
Modalities for breast screening
Mammography is commonly used as the primary screening test for breast cancer and is the screening modality recommended by the Canadian Task Force on Preventive Health Care.
All provinces and territories, with the exception of NU, perform mammography screening within organized screening programs.
Currently, no provinces or territories recommend clinical breast examinations.
All provinces and territories are currently using digital radiography (DR) equipment to screen individuals. QC is also using computed radiography (CR).
Most mammography screening is occurring in hospital settings. Other locations where screening is taking place are in mobile units, screening centres, and private clinics.
