Breast Cancer Screening

Breast cancer screening is the regular examination of a woman's breasts to find breast cancer early.

If breast cancer is found when it is small:

  • There is a better chance of treating the cancer successfully.
  • It is less likely to spread.
  • There may be more choices for treatment.

Mammography (breast x-ray) is the best screening test for most women.

If you have questions about breast cancer and screening, visit Cancer Care Ontario's website for more information.

Our Oshawa, Bowmanville and Ajax Pickering hospital sites have breast cancer screening services through the Ontario Breast Screening Program (OBSP).
