Canadian Task Force on Preventive Health Care Guidelines
The Canadian Task Force on Preventive Health Care (2011) recommends the following for breast cancer screening amongst average risk women:
Mammography• For women aged 40-49, routine screening not recommended
(Weak recommendation; moderate quality evidence)• For women aged 50-69, routine screening every 2 to 3 years
(Weak recommendation; moderate quality evidence)• For women aged 70-74, routine screening every 2 to 3 years
(Weak recommendation; low quality evidence)
Magnetic Resonance Imaging• Routine screening not recommended (Weak recommendation;
no evidence)
July 2015
Canadian Task Force on Preventive Health Care Guidelines, cont’d
Clinical Breast Exam• Routine screening for breast cancer is not
recommended when performing clinical breast exam alone or in conjunction with mammography (Weak recommendation; low quality evidence)
Breast Self Exam• Routine practice of breast self exam is not advised by
the Task Force (Weak recommendation; moderate quality evidence)

High Breast Density Recall and Recommendations
Five provinces and territories recall women based on high breast density.Recommendations following a high breast density reading varies across the country.
Automatic annual recall based on breast density
Value considered high breast density
Recommendation for high breast density levels
Northwest Territories > 75% Annual recall
Saskatchewan >75% Annual recall
Ontario > 75% Annual recall
Nova Scotia >75% Annual recall
Newfoundland and Labrador >75% Annual recall

High Risk Screening: MRI Referral Guidelines
Self-reported family history (>=2) of breast cancer (first degree relative)
Self-reported family history of BRCA 1/2
Genetic testing BRCA 1 or 2
Risk of breast cancer >20% (scored by validated assessment tools)
Chest irradiation between the ages of 10 and 30 years
Li-Fraumeni syndrome, Cowden syndrome, or Bannayan-Riley-Ruvalcaba syndrome
e-cadherin mutation
British Columbia * **
Alberta
Ontario ⱡ *** **** ***** ⱡ ⱡ
Nova Scotia ****
Newfoundland and Labrador
(>=3)
Currently there are five provinces (British Columbia, Alberta, Ontario, Nova Scotia, Newfoundland and Labrador) that have developed standard guidelines for MRI referral.
Table: The criteria or evidence that MRI referral is based upon per province
*British Columbia allows women with a 50% risk of BRCA mutation who have not yet received their BRCA testing
** British Columbia includes the following syndromes: Li Fraumeni Syndrome, Cowden’s Syndrome, HDGC (CDH-1), Peutz-Jegher’s Syndrome
***First degree relative, and have declined genetic testing themselves
**** ≥25% using validated assessment tool
***** Chest irradiation before age 30 and at least 8 years prior to the screen
ⱡ Upon confirmation of high risk status after genetic assessment
High Risk Screening: MRI Referral Guidelines, cont’d
Ontario has implemented an MRI screening component to its organized screening program for women considered at high risk for breast cancer.
British Columbia, Nova Scotia and Alberta have established guidelines for the use of MRI among women considered to be at high risk (i.e. in British Columbia the women considered are confirmed cases of BRCA1 and BRCA2 mutation only). For more information on MRI guidelines for Nova Scotia please visit http://breastscreening.nshealth.ca/guidelines.pdf
Newfoundland and Labrador is exploring the appropriateness of using MRI among women considered to be at high risk

Quality Assurance:Client Satisfaction Surveys
Northwest Territories, British Columbia, Alberta, Manitoba, Nova Scotia and Newfoundland and Labrador evaluate client satisfaction on an ongoing basis.

Quality Assurance:Evaluation of Radiologist Performance
Most provinces and territories evaluate radiologists on their level of performance on an annual basis with the exceptions of Yukon and Prince Edward Island. New Brunswick collects this data but does not report on it.

Nova Scotia 2,000 / year
Newfoundland and Labrador

*Includes diagnostic and screening mammograms**All radiologists greatly exceed this number*** New Brunswick program policies stipulate that the RHAs must have a system for the annual review of mammography screening outcome data with Radiologists† This figure is currently under review and will likely be changed to align with CAR MAP requirements.ᶲ For Northwest Territories, the level of performance is done on the program as a whole (not specific radiologist) due to small volume numbers.
