Summary

This study tests whether the Stockholm3 blood test can accurately detect when low-risk prostate cancer becomes more aggressive in men who are closely monitored instead of treated immediately. Researchers will enroll 350 men on active surveillance to see if the test can reduce the need for repeated, invasive biopsies. The goal is to make monitoring safer and more comfortable for patients.
