I must contribute to this discussion. My research has been focusing on iodine. First of all, there are thousands of hits from a Google Search on "Iodine Cancers." Also many more on "Iodine Pancreatic."
My own wife has just discovered breast cancer, and we have immediately started her on Iodine Therapy. Iodine Therapy is well documented and time tested with many doctors supporting it. Here is a copy of my own research on Iodine which includes testimonials, doctor reports, and many supporting links. http://tinyurl.com/Iodine-Kills-Cancers
It works because iodine is used by our immune system to kill cancer cells. Iodine is also required for good health, and most people are are dangerously deficient. So please do more to increase the immune system such as healthy foods, no sugary drinks, etc. CANCERS THRIVE ON SUGAR, so avoid it.
Iodine Therapy is easy & inexpensive to do, and so can be mixed with any additional therapies you may find, except Chemo Therapy. Chemo destroys the immune system and makes iodine useless. Also most cancers are the result of iodine deficiency. All of this is covered in my research report.
