Tobacco smoke has been classified by IARC as a Group 1 carcinogen (4). The body uses several mechanisms to remove carcinogens or repair/remove damaged cells: Radionuclides are carcinogens, whether or not they are toxic, because they emit alpha, beta, gamma, or neutron radiation that can ionize tissues. Examples of the chemicals which have been identified in tobacco smoke as carcinogens, and linked with the development of cancer, are presented in Table 2.
