When should I start screening for breast cancer?

Cancer screening should occur when people are healthy and have no signs or symptoms present. Women can book a free mammogram with the Ontario Breast Screening Program (OBSP) if they meet the following requirements:

• You were born a female or are trans-feminine with 5+ years of cross-sex hormone use
• You are between the ages of 50-74
• You have no personal history of breast cancer
• You have no current concerning breast abnormalities
• You do not have breast implants
• You are an Ontario resident

Women aged 30-69, identified as high-risk for breast cancer should have a mammogram and MRI every year. If you are not sure if you are eligible to be screened for breast cancer, speak to your health care provider about what screening options are best for you, or click here for more info.

How to Prepare for your Mammogram

• Arrive at your appointment 20 minutes early

• Bring your OHIP card

• Do not wear deodorant or talcum powder [wipe off any residue from the day before]

How to Book your Mammogram

Call the OBSP toll-free number at 1-800-668-9304 to find the most convenient OBSP mammogram imaging site for you. You will then be connected to book directly with the OBSP site nearest you.
If you meet the above criteria, you do not require a doctor’s referral.
