Cancer of the throat that stems from a human papillomavirus infection responds to treatment better than throat cancer that’s triggered by other causes, researchers report online July 29 in Cancer Prevention Research.

The scientists also find that blacks are less likely than whites to have throat cancer that’s attributable to HPV, which may explain why the cancer also proved more deadly in blacks in this study.

The cancer has been linked to smoking and alcohol use, but it can also arise from HPV infections acquired via oral sex (SN: 5/12/07, p. 291).
