Abstract
Colorectal cancer incidence has increased significantly in Saudi Arabia in the last few years. Although protocols and guidelines for colorectal screening programs had been established to start at age 45, adherence to screening remains low. This review aims to identify the potential barriers to participating in the screening program among the public aged over forty-five in Saudi Arabia. A significant lack of awareness about colorectal cancer and screening programs had found among Saudi Arabia's public (SA). The acceptance rate significantly increased due to health care provider recommendations. Knowledge about colorectal cancer and screening program and outcome should be raised among the public through campaigns and physicians by training established for primary health care providers regarding screening programs recommendations.
Highlights
Colorectal cancer (CRC) is the third most common cancer worldwide and the second leading global cause of mortality (Keum and Giovannucci, 2019)
Knowledge about CRC In the capital city of Saudi Arabia (SA), Riyadh, a cross-sectional study has been conducted of 484 Saudi participants aged over 45, illustrating that about 69% had heard about CRC
In an additional survey conducted in King Abdulaziz University targeting 525 unregulated students, half in the medical faculty, 82.3% had awareness about CRC, and more than half (68%) thought it was a preventable disease (Imran, 2016; Zubaidi et al, 2015a; Alshammari et al, 2020; Al-Sharif et al, 2018) found that the level of knowledge increased with age
Summary
Colorectal cancer (CRC) is the third most common cancer worldwide and the second leading global cause of mortality (Keum and Giovannucci, 2019). It expected to rise the mortality rate globally to 60% by 2030 (Aziz and Allah-Bakhsh, 2018). In Saudi Arabia (SA), CRC is second-highest cancer. The most affected age group was over 45, and a quarter had meta-static cancer (>70% diagnosed late). The late-onset presentation group (diagnosed above 45) accounted for the highest incidence. Due to delays in seeking medical attention, approximately one-quarter of late-onset presentations present distant metastasis. More than half of diagnosed cases are sporicidal with no predisposing family history or genetics (Keum and Giovannucci, 2019)
