Overview of screening action plan, risk communication & follow-up procedures by estimated risk level.

Risk Level	Risk Communication a	Screening Action Plan	Follow-Up
Average 10-year absolute risk equivalent to lifetime risk of <15%	Risk Letter: includes risk level and range	40–49 years: No regular screening with a mammogram	Phone call with study genetic counsellor or nurse available upon request
	Average risk: “In this risk level, up to <number> out of 1000 women your age may get breast cancer over the next 10 years”.	50–69 years: Screened every 2 years with a mammogram	Follow-up with questionnaire at time of risk communication and 1 year later.
Higher than Average 10-year absolute risk equivalent to lifetime risk of 15 to <25%	Risk Letter: includes risk level and range	Ontario 40–49 years: Talk to primary care provider about screening with a mammogram every year.	Phone call with study genetic counsellor or nurse available upon request
	Higher than Average risk: “In this risk level, about <number> to <number> out of 1000 women your age may get breast cancer over the next 10 years”.	50–69 years: Screened every year with a mammogram	Follow-up with questionnaire at time of risk communication and 1 year later.
		Québec Screened every 1–2 years with a mammogram, ultrasound considered if breast density is >75%
High 10-year absolute risk equivalent to lifetime risk of ≥25%	Risk Letter: includes risk level and range	40–69 years: Screened every year with a mammogram and magnetic resonance imaging (MRI)	Phone call with study genetic counsellor or nurse
	High risk: “In this risk level, <number> or more out of 1000 women your age may get breast cancer over the next 10 years”.		Follow-up with questionnaire at time of risk communication and 1 year later.

^a Women are encouraged to discuss their risk level and screening action plan with their primary care provider. In Quebec, the risk letter is also sent to the family physician. Additional materials supporting risk communication for both women and their primary care provider include: A booklet/Information sheet on Understanding your Assessment, the study Website also includes information to support understanding your risk assessment as well as many other resources (e.g., frequently asked questions).
