Killing Tumors Without Chemo: Sci-Fi Treatments Already in Hospitals with Dr. Mina Makary
May 14, 2026
In part two of this deep dive, host Chris St. John and Dr. Mina Makary explore the "sci-fi" reality of modern interventional radiology. From ultrasound waves that destroy tumors without a single incision to embolization procedures that treat chronic pain and enlarged prostates, Dr. Makary reveals how the "fourth pillar" of cancer care is making major surgery a last resort rather than a first step.
The gap between medical possibility and patient awareness has never been wider. In this episode, Dr. Mina Makary, a leader in clinical informatics and interventional radiology at The Ohio State University, dismantles the idea that cancer treatment always requires systemic chemotherapy or invasive surgery.
Dr. Makary introduces Histotripsy, a groundbreaking technology that uses ultrasound waves to mechanically destroy tumors without even a needle poke. The conversation expands beyond oncology to address everyday quality-of-life issues: treating knee arthritis with Genicular Artery Embolization to avoid joint replacement, and providing non-surgical solutions for uterine fibroids and prostate enlargement. This episode is a tactical roadmap for patients and providers looking to leverage technology that treats disease at its "doorstep" while preserving the body’s integrity.
What You’ll Learn:
- Interventional Oncology (IO): Why IO is now considered the "fourth pillar" of cancer care alongside medical, surgical, and radiation oncology.
- Histotripsy Explained: How ultrasound-induced "cavitation" can kill a tumor non-invasively, leaving no mark behind.
- The "Doorstep" Delivery: The mechanics of Y-90 and TACE, delivering radiation or chemo directly to a tumor while sparing the rest of the body.
- Chronic Pain Solutions: How blocking abnormal blood vessels (GAE) can provide up to 24 months of relief for knee arthritis.
- Uterine and Prostate Health: Why "minimally invasive" shouldn't just be an option, it should be the first trial before major surgery.
