Breast Cancer Screening
Breast cancer is one of the most common cancers for women in Ontario. 1 in 9 women will receive a breast cancer diagnosis in her lifetime.
Ontario Breast Screening Program (OBSP)
People ages 40 to 74 have a lower risk of dying from breast cancer when they are screened regularly with mammograms. Screening can find breast cancers when they are small, less likely to have spread and more likely to be treated successfully.
Breast Cancer Screening (Average Risk)
Your age and family medical history helps determine when you should get screened.
If you are between 40 to 74 years of age, the Ontario Breast Screening Program (OBSP) recommends having a mammogram every 2 years. There are other criteria you need to meet to participate in the OBSP:
- - Do not have breast cancer symptoms (i.e., asymptomatic);
- - Do not have a personal history of breast cancer;
- - Have not had a mastectomy or top surgery;
- - If transfeminine, have had at least five years of feminizing hormone use in a row;
You do not need a referral from a doctor or nurse practitioner to schedule a mammogram.
Call 1-800-668-9304 to schedule your mammogram. You can also choose to call one of the Breast Screening Programs listed below.
Your mammogram may indicate that you have dense breasts. To learn about breast (chest) density, how you can find out your density, how density can affect your health and recommendations for screening (checking) your breast (chest) density visit: Cancer Care Ontario
