Prostate cancer develops in the prostate gland, affecting millions of men worldwide. Risk factors include age, family history, and race. Early-stage prostate cancer may not cause symptoms, but advanced disease can lead to urinary problems, erectile dysfunction, and bone pain. Diagnosis involves blood tests, digital rectal exams, and prostate biopsy. Treatment options depend on the cancer stage, size, and location and may include active surveillance, surgery, radiation therapy, hormone therapy, chemotherapy, or immunotherapy. Prognosis varies, with early detection crucial for better outcomes. Screening recommendations vary, with shared decision-making between patients and healthcare providers essential.
