Prostate cancer is the most common cancer among men. It develops in the prostate gland. Some key risk factors include age, family history, and ethnicity. Staging of prostate cancer involves determining the extent of spread using the TNM system. Treatment options depend on staging and include active surveillance, surgery, radiation therapy, hormone therapy, and chemotherapy. Common side effects of treatment include erectile dysfunction, urinary incontinence, and loss of sexual desire. Nursing care focuses on managing side effects, preventing infections, maintaining skin integrity, and providing psychosocial support.
