Potential Effect of Antiplatelet and Anticoagulant Therapy on the Timing of the Diagnosis of Bladder Cancer

The most common presenting symptom of bladder cancer (BCa) is hematuria. However, the use of antiplatelet or anticoagulant therapy (AAT) is increasing. We report for the first time in published studies that patients diagnosed with BCa at an emergency room visit for an episode of macroscopic hematuria will have a lower tumor grade and stage if they were receiving AAT during the hematuria event.
