Let me add that there is a simpler and less expensive way of killing the cancer microbes than by use of an expensive Rife machine. It is with a DC Electrifier. Direct current has been shown to be effective against cancer tumors since 1959. (info) And any good Beck type blood electrifier can kill the plenteous cancer microbes in the bloodstream. I´ve helped people with this method successfully. They just changed their diet and used electromedicine.
