Background: There is little research regarding whether working as a physician affects cancer risk. Moreover, thereis no research on cancer prevalence among physicians in Korea. This study utilized the Korea National Cancer IncidenceDatabase to determine whether the prevalence of cancer among physicians differs from the prevalence ofcancer within the general population. Methods: We analyzed the medical records of a representative sample of 382 doctors who underwent a health examinationbetween 2010 and 2013 at a health examination center in a Ewha Womans University Medical Center. Cancer incidence was measured as cases that were eventually diagnosed as cancer according to a biopsy. Results: We collected medical records from 382 physicians (mean age, 51.9±8.1 years) and calculated the standardizedprevalence ratios compared to the general population. Thirty physicians (9 male and 21 female) were identifiedas having cancer. Physicians had a significantly higher prevalence of cancer compared to the general population. Cancer prevalence in male physicians was found to be 2.47 times higher than the prevalence expected withinthe general population (P=0.006). Among female physicians, cancer prevalence was 3.94 times higher than that inthe general population (P<0.001). Conclusion: This study revealed that physicians had a higher prevalence of cancer compared to the general populationin Korea, which suggests that there may be a problem present in the health care of physicians. Changes to theworking environment of physicians will be needed to reduce the high prevalence of cancer among physicians.
