I'm a big fan of Rife. Royal Rife was curing cancer in the 1920s/1930s with the technology available then. Rife Machines are relatively inexpensive, and used ones even more so. The frequencies are readily available online. If possible, best to go with an experienced Rife practitioner, since there are other things going on that led up to the cancer. Basically, Rife is based on the fact that everything is energy, and that "disease" occurs when things get out of balance. Rife restores the energy back to a healthy balance.
