The purpose of this study is to determine whether an investigational test can assist doctors in evaluating patients at risk of developing bladder cancer with the express purpose of detecting these cancers early, when they are more curable. Participants will be asked questions about race, height, weight and tobacco exposure. Medical records may be accessed to obtain study data, and patients will provide a urine sample. Researchers aim to determine the likelihood of conducting a larger trial in this setting, as well as learn whether a biomarker test is helpful in detecting bladder cancer. A biomarker is a biological molecule found in blood, other body fluids or tissues; it may be a sign of a condition or disease and can be used to predict someone’s response to a specific treatment.
