Guys should encourage their caregivers to routinely screen them for early signs of anal cancer, according to a new study. Researchers, reporting in the April 1 edition of the Journal of Infectious Diseases, found that virtually all HIV-positive men who have sex with men are anally infected with the cancer-causing human papillomavirus. Analysis of participants revealed that 97.9% of the 247 men studied were anally infected with HPV, 90.9% carried multiple strains, and most had at least one high-risk viral strain linked with anal cancer. Worse yet, few of the HIVers were able to naturally clear the most risky strains from their bodies--and many of those who did eventually became reinfected.
