yes I was thinking the Rife machine but I also thought about the guy here in the US whose wife had cancer and one night he sat down and designed a type of radio frequency machine (not Rife) that was proven to heal his wife (was interviewed on major tv stations etc). Device was purchased by major company and never heard from again.
Honestly, I believe there are many devices/ medicines/etc that have already been created to heal or cure cancer but I believe the really big guys do not want that out there...way too much money to be made off cancer.
