mindy....i am so sorry about your mother. this post touched me. we have a few things in common.....but i wish cancer was not one of them.
my dad is 74 and has stomach cancer, i will be 40 in january, and i am the youngest of 6. i too am the primary caregiver. my 3 brothers aren't handling the news well and haven't been around to help ( they also live 2-3hours away) and 1 of my sisters lives in AZ and the other in MO. we live in WI. so...it's me and my mom. and my wonderful hubby. i have a 3yr old daughter with severe autism....so things here are hectic too.
1st...if the dr's say that she can do radiation w/ no major problems. go for it. at this point you want to see if they can get the tumor to shrink. i have read that some patients aren't surgical candidates...and then after radiation or chemo they are.
get as much info as you can. ask the dr's what to do. contact the "cancer navigator" at the hospital and see what that person can do to help you out with all this info. other things you can do" see a nutritionist, see an alternative meds dr, have her eat very healthy,have your mom take walks to keep things moving, juice green verggies, don't let her eat too much sugar as it is said that cancer thrives on sugar. try anything you can.
but...be sure to try to take time for yourself too. you sound like you have a full plate. maybe seek out a cancer support group to help release.
my thoughts are with you. this is a very trying journey. take care, kris
