You are not that far from Indiana University, which has a National Cancer Institute-designated cancer center (the entire list of NCI cancer centers is
here ). Getting a second opinion from such a center is critical; doctors there will have the latest information on treatments, research and clinical trials.
Here is information about the IU head and neck center. There is contact information on the left side of that page.
Cancer Treatment Centers of America is not on the NCI list.
All the best --
