what Rife found was a marvelous way to halt and destroy cancer. What he did not find was a way to correct the underlying causes, by and large, that caused the cancer to begin with. That is why today, people with advanced cancer could use the Rife machine to buy time and allow a protocol that does cure the underlying causes to be successful.
Since few people have access to a Rife machine (there are some out there), a good alternative might be Inositol/IP6, which also destroys cancer and tumors but does not provide the answer for correcting the underlying causes.
