Hi everyone I just found out recently that my dad has lung cancer at the age of 54 we r currently in a private hospital paid fir by his employment wen we received the results by post it's says that it's spread from lung to liver and spine and staged this as 4 he's had radio on his spine and upper shoulder and 2 sets of chemo 3 weeks apart he's doing so good I can't believe it no side effects nothing no pain he's walking around no loss of appetite nothing the only thing is he thinks its stage 1 as we haven't told him that it's not curable I think it's mind over matter I wouldn't know wat to do if he was negative , my question is how long can someone last having this why is he not ill ??? Thanks in advance
