Fighting Cancer

I'm a mom of 5 boys & was diagnosed June 14 2017 with Gastrointestinal Stromal Tumor (GIST) for short. I do weekly blood test and infusions every few weeks. I'm unable to do chemo because of my spleen but do take chemo pills and I do target radiation therapy to kill the cells in & around the tumor. I've done/ tried every option available to shrink or kill the tumor but my insurance isn't very good. They pay 80% I pay the other 20%. We've spent over 20k, used our savings, took out loans, borrowed but there's nothing left for me to have the surgery to remove the tumor. I still need blood too and everything is so expensive. I've been told by the doctors that if it grows more & the chance is greater the longer it stays inside, that if once it hits my organs, there will be nothing left they can do. I have 2 tumors; one is in my lower intestine the (gist), the other is on my liver. My goal is to have them both removed, but the gist on the lower intestine is most important. I can't take alot of meds available because I also have kidney & liver disease. I just wanna live again, pain free, run with my boys & watch them grow.
