Here is a list of CCC's. Studies have been done regarding patients who go to CCC's vs other treatment centers. They have found patients do better when they are treated by the country's top doctors who are more familiar with treating 100s of cancer patients.
List of Cancer Centers If there are CCCs you want to go to, there are free flights thru different organizations and free lodging as well. But its up to you whatever you choose to do. I know you said your father is not an oral cancer patient so its not easy for me to give any advice. The top CCCs have different specialties so take some time to review the list and maybe something will work for your fathers situation.
Good luck!!!
