Lung Concer

My Dad was diagnosised with lung cancer Feb 07.  He had the lower lob of his lung removed but had no chemo or radiation---the MD's said it was a stage 1 and they got it all.  Then in May 08 the cancer was back with a rengence.  Surgery is not an option.  Radiation and chemo was the suggested TX.  We did get a second oppinion which was confirmed.  My concern is the amount of weight he has lost--50lbs in 6 weeks.  Is the the norm?  Also he is unable to swallow because of the radiation.  He has gotten dehydrated on at least 4 times and had to get fluids.  My problem is that he lives in Biloxi, Ms and I live in Atlanta, Ga.  I am onl able to get down there about once a month due to family obligation at home ( I am raising my two grandsons and they are VERY ACTIVE boys). I do not think moving down there with the boys would be a good idea.  How do I find Home Health care in his town?  Thank you for any help or suggestions anyone might have.
