By: Anna AzvolinskySource: JNCI Journal of the National Cancer Institute Advance AccessPublished:  August 29, 2013  Deaths from the major cancers—lung, colorectal, breast, and prostate—continue to decline, a trend that started in the early 1990s. Cancer incidence is also declining, if slightly, for both sexes. That’s the good news from the annual Report to the Nation on the Status of Cancer, a joint research effort by the American Cancer Society, the Centers for Disease Control and Prevention, the National Cancer Institute, and the North American Association of Central Cancer Registries (J Natl. Cancer Inst. 2013;105:175–201). But the study also shows an uptick in rates of anal and oropharyngeal cancer, a type of head and neck cancer related to infection with the human papillomavirus (HPV), in the 10-year period ending in 2009. Cancer of the oropharynx increased among white men and women (3.9% and 1.7%, respectively). Anal cancer also increased in both sexes, with the greatest increase among black men (5.6%) and white women (3.7%). Rates of vulvar cancer, another HPV-related cancer, also increased among women despite continued lower rates of cervical cancer. Researchers attribute this rise in HPV related cancers to more HPV infections. “We think that increases in oral–genital sexual practices and increasing number of sexual partners that occurred some 30 years ago as part of the sexual revolution may be implicated in part of the increase in cancer rates we are seeing today,” said Edgar P. Simard, Ph.D., M.P.H., senior epidemiologist of surveillance research. Although rates of HPV infection from three decades ago were not available in the joint report, a trend exists of men and women now in their 50s and 60s having the highest rates of both oropharyngeal and anal cancers. To directly relate HPV infection [...]
