He also pulls back the curtain on the hidden downsides — from false alarms and unnecessary biopsies to the emotional toll of worrying about things that were never dangerous in the first place.Instead of one-size-fits-all screening, he explains why personalized risk assessment, smart testing, and an ongoing relationship with a trusted physician are the real keys to staying healthy as we age.If you’ve ever wondered whether a whole-body scan is worth it — or worried you might be missing something — this episode will help you feel informed, grounded, and empowered to make the right decision for you.
