Re: My dad has cancer...desperate for answers

"Sadly, time can not be turned back. These (radiation and chemo) are the worst things to do as they destroy the immune system which is the one thing that can stop cancer."

Tell me, how many cancers have you cured?  Until you yourself have been diagnosed with lung or any other form of cancer, you have no idea how you would react.  I know the individual reaction from a laboratory diagnosis.  It isn't a fun trip.  It would be interesting to follow you for a while if you are ever diagnosed with cancer to see which treatment you would ultimately take.
