Pee test could replace some painful bladder checks for cancer patients

This study is testing whether a simple urine test that looks for tumor DNA can help some bladder cancer patients safely have fewer cystoscopy exams. Cystoscopy involves inserting a camera into the bladder and can be uncomfortable. The trial will enroll 56 high-risk patients who have already completed initial treatment. Half will follow standard surveillance, while the other half will use the urine test to guide how often they need cystoscopy. The goal is to see if the urine test can reliably detect recurrences so that patients can avoid unnecessary procedures.
