Sanjay Mehta is a radiation oncologist with over 20 years of experience at St. Joseph's Medical Center in Houston, Texas. In this episode, Sanjay explores the rapidly evolving field of radiation oncology, addressing common misconceptions about radiation exposure. He delves into radiation's critical role in modern oncology, examining recent advancements that precisely target tumors while minimizing damage to surrounding healthy tissues and reducing side effects, with specific insights into breast, prostate, and brain cancers. Sanjay discusses fascinating international practices involving low-dose radiation therapy for inflammatory conditions such as arthritis, tendonitis, and sports injuries, highlighting its effectiveness and potential for wider adoption in the United States. Wrapping up on a lighter note, Peter and Sanjay discuss their mutual passion for cars and reveal how this shared interest first brought them together.
