question: My 85 year old grandfather recently went into hospital with stomach pains and was diagnosed with an appendix rupture. But prior to the diagnosis, a CT scan was done and a mass on his lung was visible. A biopsy was given, but they couldnt get to the spot, so now the doctors want to do another biopsy and go through his back. Should we get the biopsy given that my 85 year old grandfather probably wouldnt be able to handle any chemo or radiation if diagnosed?
