The UCSF Cancer Risk Program was established in 1996 as a multi-disciplinary, genetic counseling service for families with hereditary cancer. The Prostate Cancer Risk and Prevention Clinic is an expansion of this program through a collaboration with the UCSF Comprehensive Cancer Center Prostate Cancer Program. Specialty-trained genetic counselors and physicians assess the personal and family history, verify cancer diagnoses, provide education and counseling, and offer genetic testing for cancer predisposition genes, when appropriate. Based on risk factors and genetic testing, the genetic counselors and physicians provide an individualized risk management program for each patient that includes recommendations for preventive measures and future screening for cancer.
