Hi - my stepdad has stage 5-6 dementia , CPOD, emphysema, and lung cancer . He recently was undergoing SBRT for the tumor (stage 1) and after three treatments was in the hospital with pneumonia - two weeks later he seems better - a little unsteady on his feet but doctor says he needs 24/7 babysitting or go to nursing home coz mom can t care for him at home with what he needs. we are confused doesn t seem bad enough for 24/7 - he was on level 2 oxygen and went up to 3, now trying him on 1.5 should he go back for the rest of treatments - it isn t seen as a cure
