The DNA repair system fixes the mutation that causes cancer.

Explanation:

Mutations that could cause cancer (such as mutations that promote uncontrolled cell growth) are often detected and repaired by the DNA repair machinery. Cancer cells are also often detected and can undergo apoptosis (programmed cell death) to prevent them from continuing to grow and proliferate quickly.
