For anyone self-treating cancer, I highly advise you at least read Dr. W.D. Kelley's 'One Answer to Cancer'.
Caveat - even before his death in January - may he rest in peace, just one of the attacks Dr. Kelley endured was a wide-spread attack via the Internet from minions who were fraudulently posting doctored versions of his research papers, books, etc. Dr. Kelley acknowledged this situation, via one of his secured sites, prior to his death. I do not know if anyone is watching guard over his legitimate information that may still be available on-line.
Before he died, the following was a site that Dr. Kelley advised was a legitimate copy of his One Answer to Cancer. In it, you will find that he discovered while curing his own pancratic cancer that coffee-enemas are critical to helping the body rid the toxins it becomes exposed to while the tumor is being dissolved / destroyed.
