I'm in this group due to a close friend's cancer. If I get cancer I'd want my actual cancer cells tested against a list of natural and probably Pharma substances to see which substances actually work to damage my cancer cells. One such test is sometimes referred to as the Greek Test. I think they actually need a biopsy type of sample for brain cancers but otherwise can use a blood sample. https://rgcc-group.com/index.php?page=test_onconomics_extracts-new http://www.laura-bond.com/2014/01/six-life-saving-tests/
I suggest that you consider using a more comprehensive anti cancer protocol including changes in diet, immune system support, detox, reduced stress, and much more. Hopefully you can have that coordinated by an integrative oncologist.
