A detailed account of Rife's inventions and discoveries is the subject of The Cancer Cure That Worked. This startling book documents events from 1913 to the time of Rife's death in 1972. Rife was an optical engineer and technician of great skill. His first success was the building of the Universal Microscope in the late 1920s. With it he was able to view the living cancer virus -- a feat our modern, high-powered electron microscopes still cannot do. His microscope used many quartz prisms and lenses, placed to compensate for losses of refraction due to air. This enabled him to view far tinier particles than had ever been seen before.
Using the Universal Microscope which he invented, he observed cancer viruses as they changed their size and form. He discovered that exposing a virus to certain frequencies of radio waves killed it quickly. Years of experimentation led to Rife's invention of the Frequency Instrument, a device that produced the exact frequencies needed to destroy various viruses.
In 1934 at the clinic in California, diseased people were exposed to the exact same frequencies that had been seen (through the microscope) to destroy the virus causing their illness. Treatments lasted only three minutes. The person would wait three days before another exposure giving the lymph system time to cleanse the dead virus from their bodies. Unlike the chemotherapy treatments currently in use, Rife's therapy was 100 percent effective and engendered no adverse symptoms.
Yet, 53 years after the arrival of Rife's Frequency Instrument, hundreds of thousands of people still die each year of diseases that Royal Raymond Rife cured.
The above is excerpted from a book review written by Deki and Jon C. Fox.

In 1987, Barry Lynes wrote the classic book on Rife history called The Cancer Cure That Worked. Rife's World of Electromedicine is the sequel, published in 2009. What is the difference between the two books? The Cancer Cure That Worked was primarily a biographical account of Royal Raymond Rife's life and work, including detailed, dated records of the events which occurred, and in-depth accounts from the people involved. Rife's World of Electromedicine, on the other hand, is a bird's eye view, short summary of the same time period and events. Instead of a detailed biography, Rife's World is an expository piece that includes brief, targeted chapters addressing each aspect of Rife's era, utilizing piercing, specific, and direct quotes and excerpts from historical documents including magazine and newspaper articles, court transcripts, Rife's own statements, and the eye-witness accounts of those who were present during Rife's lifelong achievements. Written as a short story, Rife's World is affordably priced so that everyone can read about Royal Raymond Rife. The book is a perfect gift for someone who wants to find out more about Rife but doesn't have time to read a longer book. Additionally, the new book explains what 20] years of additional research and document retrieval by a dedicated grass roots group have discovered and unearthed. Some of the previously missing, key factors in the suppressed and censored cure for cancer were lost or even locked away in physicians' closets for decades in order to prevent censors from destroying overwhelming evidence. Now, this evidence is printed for the first time in Rife's World.
