My dad was diagnosed with oral cancer in Sept. On October 29th he had surgery and removed the tumor and some lymph nodes. He went to the ENT on March 7th and was told that the cancer has returned. It is now on both sides of his mouth and the glands. I went to the onc. with him on Wednesday and he suggested radiation and chemo treatments for 6-7 weeks. You are given so much info. in such a short period of time that it 's very overwelming. We were not told what stage the cancer is in only that it look poor. What does that mean? He has lost so much weight. He is 5'8 ,126lbs. Once the treatments start how bad is it going to get for him . He is also having very bad headaches. Is this a very fast growing cancer? I will go with him Monday to meet with the radiation doctor what questions should I be asking. Please help!
