My huband Seth has Base of Tongue cancer stage 4-A and we are on the tail end of chemo and radiation (surgery was not an option because of the location of the tumor). We were not pleased with the prospect of a PEG tube, especially because they wanted it done BEFORE we started any treatments. However, we figured that "they" knew best and now, looking back, they were right. If you DON'T need to use the PEG tube, that would be wonderful. But if you DO, you certainly want to have it in place BEFORE any treatments because, at least in Seth's case, the prospect of putting anything down his poor, painful throat would probably be too much to tolerate. NOW, the Peg tube has proven to be a life-saver because that is the only way that he can take any nourishment. In fact, we have had to switch over to a pump that administers the fluid at a controlled rate because Seth was experiencing severe diarrhea because the flow rate was too fast. If you have an option, I would definately opt for a PEG tube; like I said, if you don't need it...great. But if you DO...
