Anal Neoplasia Clinic, Research and Education (ANCRE) Center

The Anal Neoplasia Clinic, Research and Education (ANCRE) Center is the world's first clinic devoted to anal cancer prevention. UCSF experts were the first to identify the link between neoplasias (precancerous lesions) and anal cancer, and they remain global leaders in the field. The center is part of the UCSF Helen Diller Family Comprehensive Cancer Center.

Anal cancer is on the rise in the U.S., and the vast majority of cases are caused by human papillomavirus (HPV). This virus is extremely common among sexually active people and can lead to precancerous changes in the anal tissue, which may progress to anal cancer.

Most of the time, a healthy immune system can clear the virus. But particularly in immunocompromised people, certain strains of the virus can persist, increasing the risk of cancer. Our goal at the ANCRE Center is to provide the close monitoring and therapies that can reduce that risk.

Our center offers a wide range of screening, diagnostic and treatment options, including anal cytology, high-resolution anoscopy, anal biopsy, infrared coagulation therapy and electrocautery therapy. ANCRE’s doctors provide top-tier care as well as conducting research on anal neoplasia, giving our patients access to the latest and best techniques and therapies.
