Although I originally gave Dr Hosmer a one-star review, I deeply regret having done so. Unfortunately, my cancer has returned, more than likely because I refused to follow his advice. Hopefully, he will allow me a second chance and agree to treat my advanced stage colon cancer. Having recently worked with a different medical team, I have come to appreciate Dr Hosmer and his team.
