Preference for Blood-Based Colorectal Cancer Screening in the Black Community

Background: Blood-based colorectal cancer (CRC) screening is a novel, less invasive screening that has the potential to improve CRC screening adherence, particularly among Black American populations, which has historically lower screening rates. We evaluated factors associated with preference for blood-based CRC screening among Black adults in church-based community settings. Methods: From October 2023 to January 2024, a cross-sectional survey was conducted over 101 adults aged 45 to 75 years at three Black churches in metropolitan Atlanta, Georgia. Demographics, CRC screening history, healthcare access, and attitudes toward blood-based CRC screening were assessed. Results: Overall, 72 participants (71.3%) preferred blood-based CRC screening. Preference was not associated with demographic or socioeconomic characteristics, screening history, or healthcare access. The most commonly reported reasons for ease of testing (83.3%), avoidance of stool collection (38.9%), avoidance of bowel preparation (36.1%), perceived fewer side effects (34.7%), and perceived lower risk (33.3%). Needle concerns were the only factor significantly associated with non-preference (p=0.034). Conclusion: Blood-based colorectal cancer screening was preferred by most Black adults and may improve CRC screening participation through greater convenience.
