Anal Neoplasia Clinic, Research and Education (ANCRE) Center
The Anal Neoplasia Clinic, Research and Education (ANCRE) Center, part of the UCSF Helen Diller Family Comprehensive Cancer Center, is the world's first clinic devoted to anal cancer prevention. Having been the first to identify the link between neoplasias (precancerous lesions) and anal cancer, UCSF experts remain global leaders in the field.
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 cancer risk. That’s why 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 not only provide top-tier care, they conduct research on anal neoplasia, giving our patients access to the latest and best techniques and therapies.
