prostate cancer

My father was diagnosed with prostate cancer Gliason score 4+4 = 8, and bone metastasis after scintigraphy. After this one, I begin to read about alternative methods, and I bought all books for GNM. We together found the problem : My sister has a problem with alcohol, so this was the big shock for him,( conflict with her, and he fail as a father(bone cancer)). Firts 8 months the results was very good. PSA decreased to 1,3. But the last one show us that his PSA is raising and the last scintigraphy showed that there is no dinamic in bone meta healing.
