How is DNA mutated by carcinogens?

DNA breakdown. Carcinogens can cause cells to rapidly divide in response to the continual attack on their survival. With this high cell turnover coves oxidative/free radical damage (stealing of electrons) and in many case errors in dna sequencing resulted in a mutated dna stand. The body sees this imperfect dna strand as a foreign invader and eliminates it through the immune system.
