"Increasingly, scientists are implicating HPV-16, and in some cases 18, the same ones that causes cervical cancer. In 2006, a Swedish study of preserved surgical specimens from excised oropharyngeal cancers going back over 30 years identified HPV-16 in less than a quarter of specimens removed in the 1970s. By the 1990s, the proportion was 57 percent. After 2000, it was 68 percent. In 2007, a study published in the New England Journal of Medicine found HPV-16 in 72 percent of oropharyngeal cancers in the United States. Not proof, but based on correlations with sexual behavior, and an abundance of similar findings both here and around the world over the past few years, there is credible if not alarming medical concern that the infection is being acquired through unprotected oral sex."
HPV causes a variety of devastating diseases including cancer and RRP. What more incentive do people need to take Gardasil, which is said to prevent HPV infection at a nearly 100% level of reliability?
