My dad completed radiation in February, had a clean Pet scan 3 months ago, still can't eat, using feeding tube & we found out today that there is " activity" on his latest scan. This is bad, right? Is there any possible way this isn't bad? He had a barium test the day before the scan. Could that give a false positive? We see the rad dr & ENT next week. Will they definetly do surgery or will he have chemo again or both? How bad is if going to be? Pleae be honest. I'm sorry for all the questions, but I'm scared to death. Any help would be appreciated. Thanks!
