Hi kelly
I was wondering where your dad is receiveng treatment. My sister has been going to Walt Disney cancer institute in Orlando. She is doing wonderfully now. But during treatment she would also get so dehydrated and the peg tube was suggested ,almost as a punishment, if she did not eat. She did not get one, but I feel she would have faired better during treatment if she had. She lost much weight, but looks great and feels really good too now a year later.
