My MIL, 72, has lost a lot of weight over the past month...she is concerned but too scared to go to the Dr. Could it be anything else but the big C.?..She feels tired and "unwell" but no other symptoms. She is a long term heavy drinker 2 bottles of wine a night. She is just sticking her head in the sand but I think if it could be something else -- she would go to GP.
