Welcome to OCF. I will try to help you. I am assuming that your father is an oral cancer survivor who went thru radiation treatments. Is that correct? When did he finish radiation? Where was his cancer, tongue or jaw or both? Has he been treated at a cancer center? Im not sure what the stem cell transplant has to do with his current radiation related problems. Radiation causes many after effects which are detrimental to a good quality of life. We all have our share of these issues.

Mucous is something many of us deal with on a daily basis. Sometimes musinex will help. I take sinutab which helps my damaged sinuses which in turn produces less mucous in my throat.

Has your father seen a speech therapist? That has helped some people with the swallowing. This is something that cant be forced. If he cant swallow then sadly, he cant eat. Nobody like depending on a feeding tube but for soem people it is necessary. I have one myself.

Please add a signature when you can. Its located under the "My Stuff" tab, then profile, the box on the bottom is where you can add your fathers info. Hope I was able to give you some useful info.
