“…According to American Cancer Society, the US Multi-Society Task Force on CRC and the American College of Radiology guidelines, screening of adenomatous polyps and CRC in average-risk adults should begin at age 50 years with one of the following options: 1) annual guaiac Fecal Occult Blood Test (gFOBT) or Fecal Immunochemical Test (FIT) or testing stool for exfoliated cell DNA, 2) flexible sigmoidoscopy every 5 years; 3) colonoscopy every 10 years, 4) double-contrast barium enema every 5 years, or 5) CT colonography every 5 years (7-10). Previously, several published researches from various countries with different races and cultures have reported patient barriers to CRC screening as health illiteracy and lack of knowledge, negative attitudes about prevention and cancer, financial concerns and lack of physician's recommendation for screening tests (2,(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25). Also, in a study by Beydoun and Beydoun in US, predictors of CRC screening behaviors among average-risk older adults included older age, male gender, marriage, higher education, higher income, white race, non-Hispanic ethnicity, smoking history, presence of chronic diseases, family history of CRC, usual source of care, physician recommendation, utilization of other preventive health services, and health insurance coverage (26).…”
