I’m not saying cancel your mastectomy, but here are some things you might want to know about cancer. There are some mainstream doctors in the United States who know all the traditional therapies for cancer, but are also involved in cutting edge research too. Here are some resources. A book by Jeffrey Dach, MD. Cracking Cancer Toolkit Using Repurposed Drugs for Cancer Treatment. Also look up Dr. Mitchell Ghen, who is a D.O physician and PhD, plus holds an additional Masters degree in biomechanical trauma. Look up his name under integrative medicine. He is in Boca Raton, Florida. I believe these doctors are educated about both mainstream cancer treatment and functional and holistic therapies.
