I've read online that natural immunity from cancer is best. Just let it do its thing so that once you beat it your body is indestructible. I read an Angolan study that claimed you can get hit by a bus and you'll be ok once you just let your natural immune system beat cancer by itself. Even if the bus does hit you I read a study from Bolivia that says that you can just take this drug that Sea World gives to Shamu to eliminate water tank parasites and it'll fix your broken spine.
