Using a simple and inexpensive procedure similar to a Papanicolaou (Pap) test to screen for anal cancer among gay and bisexual men would be a cost-effective way to save lives, according to researchers at Harvard School of Public Health and the University of California at San Francisco School of Medicine.
Each year, for every 100,000 gay men in the United States, 35 develop anal squamous cell cancer, a number comparable to the 40 women per 100,000 who developed cervical cancer before the routine use of Pap tests. Both malignancies are caused by human papillomavirus.
