Mutagenicity and carcinogenicity are clearly correlated. One study showed that
157 of 175 known carcinogens (approximately 90 percent) are also mutagens.
Chemical mutagens are classified as alkylating agents, cross-linking agents, and
polycyclic aromatic hydrocarbons (PAHs). Alkylating agents act by adding ...
