This document discusses prostate cancer, including its definition, causes, risk factors, clinical manifestations, management, and nursing care. Prostate cancer is a malignant tumor that usually grows slowly and remains confined to the prostate gland for many years but can advance and spread to other tissues. Management may include radical prostatectomy surgery, hormonal therapy, radiation therapy, cryotherapy, or chemotherapy. Post-operative nursing care focuses on monitoring for complications, caring for urinary catheters, encouraging mobility, and providing routine post-operative support.
