WebTumor suppressor genes are among the most common genes protecting your body from cancer. These genes make special proteins that put the brakes on cell growth that may cause cancer. When tumor suppressor genes mutate (change), it’s as if they switch from pressing on the brakes to hitting the gas pedal, suddenly putting cell growth into overdrive. WebThe Genetics of Cancer.
