my wife (jessica, 32 yrsold) has been battling sstage four squamous cell with distant metastes in the lungs and lymph nodes now for 16 months. She wasnt a smoker or big drinker, so the diagnoses came as a big surprise. Weight loss has become a serious factor-- shes about 40 kilos/ 90 lbs. at what point should we start taking to her Dr and schedule a break on chemo so she can get some rest and gain back some weight? They seem to think she can go for several more months, but I'm not so sure and they aren't here at home every day seeing what i see.
