Cancers linked to the human papillomavirus (HPV) rose dramatically in a 15-year period, even as the rates of young people being vaccinated climbed, the Centers for Disease Control and Prevention (CDC) reported. The 43,371 new cases of HPV-associated cancers reported nationwide in 2015 marked a 44 percent jump from the 30,115 cases reported in 1999, according to a CDC analysis. HPV vaccination rates have improved over the years, but not fast enough to stem the rise in cancers, the CDC said. Oropharyngeal (throat) cancer was the most common HPV-associated cancer in 2015; accounting for 15,479 cases among males and 3,438 among females, the CDC data show. HPV infects about 14 million people each year and between 1999 and 2015 rates of oropharyngeal (throat) and vulvar cancer increased, vaginal and cervical cancer rates declined, and penile cancer rates were stable, according to the CDC.
