You have an early stage of prostate cancer that can be treated effectively with surgery or radiation. If you choose to take part in this study, you will be agreeing to receive only active surveillance. Active surveillance is an investigational way to manage low-stage small volume prostate cancer. While on active surveillance, you will have no treatment for the prostate cancer. However, you will have repeated Prostate Specific Antigen (PSA) tests, physical exams, and other testing to detect when the cancer is becoming a greater risk which may require you to begin treatment.
