Have you looked into Iodine supplementation? There is a strong link between low Iodine levels (corresponding high levels of bromides and fluorides aka halides) and cancer. High levels of bromide have been found in Breast Cancer patients, for instance. Iodine is needed by every part of the body and mucosal linings (like the colon).
Also, what about Oleander and Colloidal Silver ? Both are reputed to have anti-cancer properties. Ask Tony Issac has some good info on CS and Oleander in cancer cases. Utopia-Silver sells CS as well as oleander. You can even make or purchase a CS generator and make it yourself.
If I were in your shoes, I'd be throwing everything I could at my illness that was alternative and had good track records. Also, just came to mind....low levels of vitamin D put us at risk for something like 16 types of cancer. If your levels ARE in the tank, then you can get OTC 50,000iu vitamin D from a company called BIO TECH. I keep a couple of bottles of that strength on hand for the cold and flu season. http://www.vitamindcouncil.org,
also, I think the iodine supplementation board has a video on vitamin d on the Iodine Forum . //www.curezone.org/forums/fm.asp?i=1560518#i
