To paraphrase the Blue Oyster Cult, "Don't fear the chemo..." Sorry to hear of your mom. Clearly, something went wrong - but what would have happened without treatment? I have now had 20 drugs in 11 regimens, total body irradiation, a stem cell transplant and too much else to list. In 2015, I had three cancers simultaneously. Maybe I'm a little dense, but I chose to forge ahead and fight.
It paid off. Life is worth living.
