Both my grandparents died from cancer. By the time it was detected, it was too late for treatment in both cases. The only person I have ever seen go through chemo was my friend Tony that I mentioned. They installed a port (for lack of the correct terminology) in his chest. He had treatments like every other day at first. He'd be wiped out afterwards and go home and not come back out again that day. Said he had 0 energy. Took him a while after the treatments ended to get his stamina back to the point of even considering coming back to work.
