A Mutation occurs when a DNA gene is damaged or changed in such a way as to alter the genetic message carried by that gene. All cancer is the result of gene mutation. Example, HPV (human pappiloma virus) can mutate and cause cancer. Exposure to certain carcinogenic chemicals can cause cellular mutation and lead to cancer, example certain benzene derivatives
