I like Essiac and so does my good friend Webster Kehr "the cancer tutor", but neither of us like it as a standalone treatment. Times have changed since Rene Caisse was around working wonders, and there is still some debate about the correct mix of herbs, not to mention the harvesting and freshness of today's Essiac tea mixes compared to hers. It is still a good thing to use, I think, but I would surely want to throw more in the fight if it were me.
