Awareness of colon cancer screening among the general population: Community-based study from the Qassim Region of...

Colorectal cancer (CRC) has surged to prominence as the leading cancer affecting men and the second most common affecting women in Saudi Arabia. The need for preventative screening is underscored by the rising prevalence of precancerous polyps, early-stage colorectal cancer, and the fact that these conditions often manifest without symptoms.

This study utilized a cross-sectional descriptive design and employed data from a sample of 425 residents of Qassim region in Saudi Arabia. The participants guaranteed their confidentiality when completing self-administered online questionnaires.

Nearly half, 209 (49.2%), of the participants indicated that there were increasing incidences of colon cancer in Saudi Arabia. A considerable number [122 (28.7%)] of respondents believed that family history was the risk factor for colorectal cancer. A total of 203 (47.8%) knew that CRC could develop without symptoms. Common symptoms of CRC were cited as bleeding per rectum 300 (70.6%) and abdominal pain 259 (60.9%). The majority, 384 (90.4%), of the respondents believed that CRC could be prevented and cured if detected early, 415 (97.6%). The results noted that more females knew that there were increasing incidences of CRC in KSA (P = 0.03). Older participants were more likely to understand the function of the colon and rectum (P < 0.001**), the risk factors (P < 0.001**), and the symptoms of CRC (P < 0.001**), as well as their willingness to choose colonoscopy to conduct colon follow-up screening even without symptoms (P < 0.001**). Married participants had a higher likelihood of knowing the ranking of CRC among the most common tumors in both sexes in KSA (P = 0.027*). Participants with a higher education level were more likely to know the ranking of CRC among the common tumors in the KSA (P = 0.004**), the functions of colon and rectum (0.003**), and the symptoms of CRC (P < 0.001**).

The study revealed considerably below-average knowledge about the general public's screening for CRC in the Qassim region of Saudi Arabia. Although a substantial proportion of participants demonstrated knowledge about the risk factors, symptoms, and prevention of CRC, there is limited knowledge about screening programs in the region. This underscores the need for public awareness campaigns and concerted efforts to eliminate the obstacles preventing more people from getting screened with colonoscopies for early detection and prevention of CRC.
