Brian,
Thank you for your response.I took your advise and did some searching,you were exactly right I located some great info!I found out from the GI doc today that the reason he is having difficulty with cold liquids is because of the difficult time they had threading the tube.He said he'll be sensitive for a few weeks.They just failed to mention this before he drank a can of ice cold "Boost".I also touched base with his medical oncologist today,we had a discussion in regard to probabilities.It seems that his cancer is so rare that they don't have enough clinical data to give any informed answers.The fact they know so little frightens me .I have spent countless hours on the net researching "oral malignant melanoma",there is just not alot out there.So I'm going to be strong for him and we're all going to learn together how to beat this thing!!!
