I've seen where people are referring to head and neck cancers. what are the specific types?
My husband who just turned 52, was diagnosed with a sinonasal adenocarcinoma. We live in Chicago but he had it surgically removed at UPMC Presbytarian, unfortunately had to go back for another surgery a week after we returned bc of a brain fluid leak, he is currently in his 2nd week of Proton Radiation therapy. We are having trouble finding an oncologist who has dealt with this specific cancer. Cant seem to find much on the internet either.
