Medical Students' Perception of Risk Factors for Cancer.

To evaluate the perception of risk factors for cancer among medical students and how it varies among students in different years of their medical education. Cross-sectional study was conducted in 2019. The American Institute for Cancer Research Cancer Risk Awareness Survey questionnaire was administered to medical students at the Centro Universitário Saúde ABC. Students were divided into those in their 1st to 3rd year and those in their 4th to 6th year of medical education. Qualitative variables were described by frequency and percentage, and quantitative variables were described by mean and standard deviation or median and interquartile range. The scores of the groups on the questionnaire were compared using Student's t test. The 95% confidence interval was calculated, and p values < 0.05 were considered significant. We included 196 students, with approximately 30 to 35 students in each year of medical education. The median age was 22 (18 to 31), with 74% being female. Among risk factors for cancer, smoking (100%), cancer-causing genes (99.48%), and excessive sunlight exposure (99.48%) were the most cited by students. We observed a significant difference in the number of correct answers, favoring students in their 4th to the 6th year over those in their 1st to the 3rd year (mean = 16.46 vs. mean = 13.73, p < 0.001). Perception about risk factors for cancer is greater in the later years of medical education.
