All I know to tell you is to spend all the time you can with your mom. My mom has lung cancer and watching her go through chemo was the absolute WORST. I didn't want her to do it, everyone else did. Hopefully there will still be good days ahead. My mom finished her chemo & radiation a long time ago and she has had many good days since. It just took a while for her to regain her strength. I don't mean to sound negative on chemo, it helps many and radiation did shrink her tumor quite a bit and buy us alot more time (she was given 4-6 months 19 months ago). It's just hard to see the suffering that goes along with chemo. God Bless.
