Cervical cancer rates are declining, but human papillomavirus-related cancers of the tongue and tonsils, as well as anal cancers, are increasing, a new study in the journal CMAJ Open says.

Researchers at the University of Calgary looked at HPV-related cancers diagnosed between 1975 and 2009 and recorded in the Alberta Cancer Registry.

The rates of oropharyngeal cancers — cancer of the base of the tongue or tonsils — increased from 1.2 to 3.7 per 100,000 men, while in women, it increased from 0.6 to 1.

Anal cancer in women doubled during the study period, from 0.7 to 1.5 per 100,000 women, while in men it changed from 1.8 to 3.8, the researchers found.

Cervical cancer rates decreased 1.1 overall.

"The increases in the incidence of oropharyngeal cancer among younger men and of anal cancer among younger women are disturbing, because there are no screening programs for early detection of these cancers," researcher Lorraine Shack said in a press release.
