Breast cancer is the most common type of cancer in women in Ontario. 

The breast cancer screening test is a mammogram. A mammogram is a breast x-ray that can help find breast cancer early.

All women aged 50 years or older should have a mammogram every 2 years. 

When having a mammogram:

  • Your breasts are pressed to take x-ray pictures and it may feel uncomfortable for a few seconds.
  • Breasts need to be pressed in order to find changes that may have started and can’t be seen or felt.
