Colorectal Cancer Rising in Young Adults: Early Warning Signs & Prevention

In this episode, I sit down with Dr. Amir Esparza, double board-certified colorectal surgeon at City of Hope, to discuss the alarming rise of colorectal cancer in patients under 45—becoming the #1 cause of cancer death in young adults. Dr. Esparza reveals warning signs often dismissed as hemorrhoids, explains why 30% of rectal cancer patients can avoid surgery through chemo/radiation alone, and shares robotic surgery breakthroughs reducing hospital stays from 7-10 days to 1-2 days. We discuss fiber's power (30g daily), why 90% of Americans are constipated, gut microbiome's impact on mood and immunity, and City of Hope's integrative approach combining surgery with acupuncture and multi-faith spiritual care.
