He is suffering from coronary artery disease (CAD) and already started 5 years back. cardiologist consultant has given Go for TURBT but has told my father to continue all medicines including aspirin. But urologist told my father to stop aspirin 4 days before surgery. Please tell me what to do. Whether I should stop aspirin or not.
