Welcome to our little corner of helping and healing !
I had the first option you posted for a rectosigmoid primary tumor :
The first opinion: 5-6 weeks radiation with chemo pill, wait 8 weeks, first surgery with a colostomy bag, 6 months of chemotherapy, 2nd surgery to reverse bag (hopefully).
that was in spring 2007
I am still here .....JMO
BUTT your Mom's Docs are really the ones to make the call for HER situation.
What I did when I got 2 opinions which differed ... get a third
BUTT please note that things have changed since my primary treatments in 2007 and ...
I know a lotta folks here have had option #2 as well
Cheers and best wishes
