My wife is in the later stage of Kidney Cancer & brain Tumour, she is on some heavy drugs to stop seizures or at least control them, but she hasn't had the appetite to eat for some time & only drinks small amounts about 200ml per day. Because we have a 16 yr old son it is really hard for him to see his mother going through this & would like to know how long my wife can last without food & limited fluids. She has been this way for about 8 weeks & has lost a lot of weight. Please help because i don't know what to expect
