title: Canadian Radiologists Do Not Support Screening Mammography Guidelines of the Canadian Task Force on Preventive Health Care.
abstract: OBJECTIVE
  The study sought to determine screening mammography recommendations that radiologists in Canada promote to average-risk patients and family or friends, and do or would do for themselves.
  
  
  METHODS
  An online survey was delivered from February 19, 2014, to July 11, 2014. Data included radiologists' recommendations for mammography and their personal screening habits based on gender. The 3 radiologists' cohorts were women ≥40 years of age, women <40 years of age, and men. The distribution of responses for each question was summarized, and proportions for the entire group and individual cohorts were computed.
  
  
  RESULTS
  Of 402 surveys collected, 97% (299 of 309) radiologists recommended screening every 1-2 years, 62% (192 of 309) starting ≥40 years of age and 2% (5 of 309) recommended screening every 2-3 years for women 50-74 years of age. Recommendations were similar for family and friends: 96% (294 of 305) recommended screening every 1-2 years, 66% (202 of 305) recommended screening every 1-2 years for women ≥40 years of age, and 2% (5 of 305) recommended screening every 2-3 years. For women radiologists ≥40 years of age, 76% (48 of 63) underwent screening every 1-2 years and started at 40 years of age, 76% (16 of 21) female radiologists <40 years of age would undergo screening ≥40 years of age, 100% every 1-2 years, and 90% (151 of 167) male radiologists would undergo screening every 1-2 years, with 71% (120 of 169) beginning at 40 years of age.
  
  
  CONCLUSIONS
  The majority of Canadian radiologists recommend screening mammography every 1-2 years for average-risk women ≥40 years of age, whether they are patients or family and friends.
