My husband was diagnosed with colon Cancer in Feb 2007. He took chemo drug Xeloda and had standard radiation. During a check up in January 2008, tumors were found in his lungs- one in each lung, sizes: 7mm and 13mm. He took chemo: Folfox, Avastin, Oxaliplatin, and Xeloda until April 2008. The April CT scan revealed that the tumors had grown slightly and that there were four more small nodules visable. He discontinued Chemo and chose alternataive therapy with High Dose Vitamin C, and B17, changed his diet, and had some blood boosters. In August a new CT showed the good news that no new tumors were visable, but that the primary tumors were slightly larger. We beleive that if the tumors could be removed from his lungs that the immune system could better help him fight off any new tumors. Will pin point radiation using Cyber Knife Treatment to a tumor in his lung help my husband?
