My father was diagnosed in August. He had six lymph nodes under his right arm that tested positive. The largest was 7 cm. He opted to do nothing after the surgery. He went for his PET at the end of November. They found three more tumors under his collarbone. They are recommending radiation, but he is not sure he wants to deal with side effects. He would like to get into a clinical study, and is pursuing that avenue. His surgery was today, so even if he is a candidate, he won't be ready to start any trials for several weeks. I have read all I can get my hands on attempting to determine a reasonable prognosis. As far as I know, the melanoma has not spread to any organs. They were not able to identify the primary site, and his is Amelanotic. Any words of wisdom?
