Answer 1

The Biology of Cancer

Cancer is a disease caused by the failure to control cell division. This results in cells that divide too often and eventually interfere with normal body function. Scientists view cancer as a disease caused by mutations in the genes that regulate cell division. The mutations can be inherited or caused by agents in the environment. For example, the tar from cigarettesmoke has been directly linked to mutations in the p! gene. The tar in cigarette smoke is categori"ed as both a mutagen and a carcinogen. #utagens are agents that mutate, or chemically damage, $%&. Carcinogens are mutagens that cause cancer.
