Bowel Cancer & Genetics: What You NEED to Know with Associate Professor Dan Buchanan

🔍  We talk a lot about breast checks — but what about bowel screening?

In this essential episode of The Aging Project Podcast, we’re joined by Associate Professor Dan Buchanan from the University of Melbourne, a global leader in bowel cancer research, genetics, and early detection.

Bowel cancer is now the second leading cause of cancer death in Australia, with a concerning rise in cases among younger adults. But here’s the good news: it’s one of the most preventable cancers when caught early.

Dan shares the latest insights from his research, including the groundbreaking ANGELS Study, and helps us understand the role of genetics, the power of early detection, and what every woman over 40 — and under — needs to know to protect their gut health. This is an empowering conversation designed to help you move from silent worry to informed, proactive health choices.
