My husband is 65, for past few months has had severe lower back pain, abdominal pain, diahrrea, loss of appetite, and short term memory getting bad. He is without a doubt an alcoholic and consumes hard liquor daily 5 plus drinks of whisky and coke. He has not proven he can go more than 3 days without drinking. After a few bites he feels full, he is losing muscle tone and is overly tired. My concern is cancer of the liver. can you advise if these are symptoms
