I doubt it could hurt!
Exactly...
It's been 25 years, and more, since I went on the Great Hunt for the Sure Cure for Cancer with my long-lost first wife... she had Kaposi's hemmoragic sarcoma, then malignant melanoma- but what set her off the deep end was when her brother got melanoma, too.
We started in Vancouver, and went all the way down to Contreras's clinic in Mexico, looking for "something- anything" that would offer an alternative to the dire prognosis from conventional medicine. Laetril, wheatgrass juice & sprouts, retinotherapy, reflexology, DMSO-- you name it, we tried it- And yes, her brother died eventually, despite the best conventional, and other, treatment...
...but...
while I remain unconvinced that "alternatives" offer any sort of sure cure, they did have snippets of knowledge that medicine poo-poos, yet- why not try diet, and exercise? Can't hurt you, you may feel better, or at least different for a while.
