title: Increased cancer risk among surgeons in an orthopaedic hospital.
abstract: BACKGROUND
  Five cancer cases over 7 years were reported in a small orthopaedic hospital where radiation protection practice was poor.
  
  
  OBJECTIVE
  To investigate whether workers subject to routine radiation dosimetric assessment in that hospital had an increased cancer risk.
  
  
  METHODS
  One hundred and fifty-eight workers subject to routine dose assessment and 158 age-sex-matched unexposed workers were questioned about cancer occurrence. All tumours were analysed as a single diagnostic category.
  
  
  RESULTS
  Cumulative 1976-2000 cancer incidence was 29 (9/31), 6 (8/125) and 4% (7/158) in orthopaedics, exposed other than orthopaedics, and unexposed workers, respectively. At logistic regression analysis, working as orthopaedic surgeon significantly (P<0.002) increased the risk of tumours.
  
  
  CONCLUSIONS
  These findings caution against surgeons' underestimation of the potential radiation risk and insufficient promotion of safe work practices by their health care institutions.
