My father was diagnosed with Oral Cancer a few months ago. They did a biopsy of his tongue, throat and gum. The only one that came back "bad" was his tongue. They removed 1/3 of his tongue this past week. He is doing great, or as great as he can be for missing part of his tongue. I went to the hospital for his surgery but because I live 5 hours away its not easy to talk to his doctor to ask the thousands of questions I have. Ive looked all over the internet to try to understand what my mother has been telling me about it but Im still so confused. He had a PET scan done and I was told his results came back 50/50. What does that mean? He had a lymph node(sp?) removed from his neck and we are waiting for the results. Just hoping someone can explain the PET scan for me while Im playing the waiting game. Thanks so much!
