New screening guidelines in Canada that state women aged 40–74 years with average risk for breast cancer do not need mammograms as often as thought, announced November 21, 2011 by The Canadian Task Force on Preventive Health Care.

The new guidelines include these recommendations for Canada:
- women under age 50 who are at an average risk of developing breast cancer should not have routine mammograms
- clinical breast exams and self-exams have no benefit and shouldn’t be used
- women aged 50 to 69 who are at an average risk should have mammograms every two to three years, instead of every year or two
- women aged 70 to 74 who are at an average risk should have mammograms every two to three years (previous guidelines didn’t recommend screening for that age group)

The recommendations don’t apply to women with an elevated risk of breast cancer, such as those with a history of the disease in a first-degree relative or those with mutations in the BRCA1 and BRCA2 genes.
