Franchesca's alternative treatment

In 2015 I was diagnosed with a rare form of cancer called "myxopapillary ependymoma with anaplastic features" since then I've had two major spinal surgeries and one brain surgery to have a shunt put in permanently to drain the fluids in my brain. I've also had multiple radiation treatments both in the brain and spine but unfortunately they haven't been as successful as we have been hoping because the tumors have continue to spread in my brain and spine, which has been causing me a lot of pain and discomfort. It has been almost three years since my diagnosis so at this point I am seeking for alternative treatments to prevent the tumors from spreading to other parts of my spine and brain. I've been fortunate enough to have my family whose been very supportive and helpful through this journey  and have done everything possible to help provide for my treatments, but at this point my  options are limited and very costly, Any help at this point would be very helpful.
