New Canadian Breast Cancer Screening Guidelines
In October 2024, Ontario announced a significant change to its breast cancer screening protocol: lowering the self-referral age for publicly funded mammograms from 50 to 40. This expansion of the Ontario Breast Screening Program (OBSP) aims to enhance early detection and treatment of breast cancer among women aged 40 to 49.
Key Changes in the Guidelines:
Self-Referral Starting at Age 40: Women aged 40 to 49 can now self-refer for mammograms through the OBSP without needing a physician's referral. This change facilitates easier access to screening for those without a primary healthcare provider.
Screening Interval Recommendations: For women aged 40 to 49 who choose to participate in screening, the OBSP recommends mammography every two years. For those aged 50 to 74, biennial mammograms remain the standard recommendation. Cancer Care Ontario
Rationale Behind the Update:
The decision to lower the screening age is informed by data indicating that nearly 20% of breast cancer cases in Canada are diagnosed in women under 50. Early detection in this age group can lead to more effective treatments and improved survival rates. University Health Network
Considerations for Women Aged 40 to 49:
While the expanded access provides an opportunity for earlier detection, it's essential for women in this age group to make informed decisions about screening. The OBSP encourages discussions with healthcare providers to understand personal risk factors, as well as the potential benefits and harms of screening.
How to Access Screening:
Booking an Appointment: Please speak with your medical team. Conversely, eligible women can schedule a mammogram directly by contacting their nearest OBSP location or by calling the OBSP at 1-800-668-9304. A tool is available to find mammogram wait times and locations.
Looking Ahead:
This policy change aligns Ontario with other provinces that have adopted similar screening guidelines, reflecting a broader commitment to women's health across Canada. As the OBSP implements this expansion, it's anticipated that earlier detection will lead to better outcomes and reduced mortality rates from breast cancer.
