Current cancer prevention initiatives for lip, oral cavity, and pharyngeal cancers are limited because of an absence of knowledge on the global incidence of these cancers by site. A new study, conducted by researchers from the International Agency for Research on Cancer (IARC), the American Cancer Society, and the United States National Cancer Institute, outlines and examines, for the first time, the number of new lip, oral cavity, and pharyngeal cancers worldwide by site, sex, and age. The study identifies stark regional variations in these cancers, hypothesized to be due to differences in exposures to carcinogens.
