Hi Amber, in response to your questions, I didn't have any feeding tube during or after treatment, although eating and drinking was a difficult task. I lost about 15 lbs without the tube and gained back the lost weight in 6 months' time. I know most patients and caregivers on this forum advocate the use of the feeding tube and there has been a lot of discussion on this issue. In Hong Kong, only about 25% of the patients need the feeding tube during treatment.It is a personal choice and you can gather more opinions before making a decision.As for major side effects, mouth/throat sore and skin burn around the neck were significant in my case. At the present moment, mouth dryness is the most frustrating effect for me. It doesn't improve and when weather is dry, I suffer more and my voice becomes more raspy. If possible, try to opt for IMRT for radiation treatment which is known to have less side effect on the patient.
Take good care of your dad and yourself. You have a tough battle to fight.

Karen
