How do you prevent yourself from getting any kind of cancer?

You can't: Genetic mutations accumulate in all of us as we get older, and thankfully the majority of us escape full-blown cancers until something else gets us. Anyone offering a scheme to guarantee you will not get cancer is scamming you. Minimize your risk by avoiding tobacco & excess sunlight & booze, getting premalignant breast / colon lesions excised, rx helicobacter. Your physician can help.
