In general, I like those kinds of tests though not so much for mainstream chemo drugs, none of which permanently cure cancer and most of which actually cause cancer or make it more likely to return even if the cancer is seemingly eliminated to begin with (and most often it isn't).
When it comes to comprehensive anti-cancer programs, if there is one out there that is more comprehensive than the one I have developed and refined over the past couple of decades (or more successful for that matter) I am not aware of it:
Interestingly, I first began researching cancer in earnest about twenty or so years ago when my own close relative was diagnosed with Stage III melanoma. He's still alive, btw. As is my 90 year old uncle who had advanced lung cancer with mets. As is likely thousands of people around the world. I didn't cure them. I just provided the information and they cured themselves.
