In this episode, Peter takes a deep dive into colorectal cancer (CRC) screening, explaining why it is one of the most preventable cancers and why getting screening right can have life-saving implications. He walks through how colorectal cancer develops and why it is uniquely well-suited to early detection and prevention, with a particular emphasis on the dual role of colonoscopy as both a diagnostic and therapeutic tool. Peter also examines the concerning rise in early-onset CRC among younger adults, highlighting why awareness and timely screening matter more than ever. The episode provides a practical guide to preparing for and evaluating the quality of a colonoscopy, including how to think about appropriate screening intervals and the real risks and tradeoffs involved. Finally, Peter explores the expanding landscape of non-invasive screening options, offering clear insight into what these alternatives can and cannot do so listeners can make informed decisions about their care at any age.
