Cindy,

Welcome to this site. I'm sorry your father has to go through this, especially at his age. I was 39 and otherwise in good health when I was diagnosed, and even then I found the latter stages of radiation really tough. Frankly I'm a bit surprised that your father got this far along before the nasty mucus started -- for many of us, it became a problem at an earlier point.

How is he doing in terms of getting enough daily nutrition/hydration? Is he still able to eat by mouth or is he using a tube? What kind of pain management assistance is he getting from his doctors? Is it possible that he had any recent medication change that could have caused the vomiting? Is there someone who is living/staying with him all the time to monitor his condition?
