You need to go somewhere you are comfortable, confident in the treatment, and is willing to get second opinions. My wifes ENT here, when we went over the first biopsy said that he would go to Memorial Sloan Kettering or MDA for cancer, and to Mayo if there was uncertainty in diagnosis or treatment. Since we were familiar with MDA from our years living in Houston, it was an easy choice for us.
Good luck @Dbeasy , I think it all depends on your diagnosis - there are only 1 or 2 places on the planet who have a treatment for my wifes cancer. But if you have a more common type then there are certainly other choices. I will say, maybe again, that we met several people during radiation, and there were at MDA because they were misdiagnosed in their first treatment, and therefore the treatment was not successful; and they were at MDA with a new diagnosis, then going through an entire second treatment regimen. One of the things that is on some of the MDA advertising is a slogan "where you go first for treatment matters" - we have come to believe that.
If nothing else, it is certainly worth getting a second opinion to confirm diagnosis and treatment.
