Williams Cancer institute – Mexico City

When you have cancer, you don’t have time to wait for today’s scientific advances to become standard treatment years from now, you need those today.

Jason R. Williams is a medical doctor, board-certified radiologist, image-guided cancer specialist, researcher, and professor. He is one of the pioneers of immunotherapy, specializing in intra-tumoral interventions. He performed the world’s first ablation procedure and implemented an intra-tumoral injection of a specific combination of immunotherapy agents, thus leveraging the actual process of ablation as an immunotherapy agent itself. Since then, he has performed thousands of procedures many of them “first in human” in multiple areas of ablation and cryoablation therapies.

Dr. Williams is the Director of Interventional Oncology and Immunotherapy at the Williams Cancer Institute, where he has been advancing the use of intra-tumoral immunotherapy. He is also an adjunct professor at Case Western Reserve University in Cleveland, Ohio, where he is helping to further cutting-edge research. In addition, he is actively involved in private research combining numerous different immunotherapy agents for image-guided intra-tumoral injection covering almost all cancer types. He and his wife, Stefanya Williams live between Fort Lauderdale and Mexico City. To learn more about Dr. Williams and his clinic, submit the form on this page.
