Prostate cancer is a common malignancy in men, typically affecting those over 50 years of age. It develops when abnormal cells in the prostate gland grow uncontrollably, potentially affecting urinary function and, in advanced cases, spreading to bones or lymph nodes. Early stages may not show noticeable symptoms, which makes regular screening with PSA (Prostate-Specific Antigen) tests and digital rectal exams important. Depending on the stage and aggressiveness, treatment options include active surveillance, surgery, radiation therapy, hormone therapy, or chemotherapy. Early detection greatly improves prognosis and quality of life.
