Colorectal cancer is no longer just a disease of older age; cases are rising rapidly among adults under 50, making it the leading cause of cancer death in this demographic. While medical guidelines adjusted by lowering the recommended screening age to 45, actual patient behavior has not followed suit. This post explores the widening generational divide in cancer data, why traditional bowel prep remains the ultimate barrier to early detection, and how Zera Medical is working to reshape the screening experience.

A colonoscopy is only as good as the prep that comes before it, and up to a third of procedures are compromised by inadequate bowel preparation before the scope is ever advanced. This post breaks down what that failure actually costs: missed lesions, repeat procedures, destabilized clinic schedules, and real erosion in screening economics. It makes the case that inadequate prep is a structural problem built into the at-home model, not a patient failure, and points to ZeraFlow as a clinic-based way to fix it at the source.

Most people who put off a colonoscopy aren't afraid of the procedure. They're avoiding the prep, and the research backs them up: only about a third of newly eligible adults are getting screened, with the at-home preparation cited as the barrier patients dread most. This post looks at why traditional prep drives avoidance, how skipped or failed screenings translate into missed cancers, and why fixing the prep may be the highest-leverage step in colorectal cancer prevention. It also introduces ZeraFlow, our clinic-based approach to removing that barrier.
