Read our Prostate Cancer research guide →This is an observational study—meaning researchers watch and collect information rather than test a new treatment. If you have early-stage prostate cancer and have decided to use active surveillance (careful monitoring instead of immediate surgery or radiation), this study invites you to join a structured follow-up program. Researchers will track your imaging scans, medical visits, and quality of life over time to learn more about how early prostate cancer behaves in men who choose to wait and watch.
Many men with early-stage prostate cancer live long, healthy lives without immediate treatment. This study exists to better understand how often the cancer progresses, how long men survive, and how the monitoring approach affects quality of life—so doctors can give future patients better information about active surveillance as a safe option.

You would join a long-term follow-up program where your medical team regularly monitors your prostate cancer through imaging studies, clinical exams, and possibly repeat biopsies. The study collects information about your disease status, any changes over time, and how active surveillance affects your quality of life. There is no experimental medication or treatment involved—this is purely a structured observation and data-collection program designed to build knowledge about how early prostate cancer progresses in men who choose monitoring instead of immediate intervention.
