The Prevent Anal Cancer (PAC) Study

black-gay men

About the Study 

There is a much greater risk for anal cancer among gay and bisexual men, especially gay and bisexual men who are HIV-positive. But we don’t know the best way for people to get screened.

The PAC Study aims to change that. This study will find ways to detect anal cancer earlier, when it’s much easier to treat.

We will enroll gay and bisexual men and transgender women into a one-year study. Participants will receive up to $130 to help us learn better ways to find anal cancer.

This study is funded by the National Cancer Institute at the National Institutes of Health. It is being led by researchers at the Medical College of Wisconsin in partnership with community-based organizations, community clinics, and other universities.
