What is Prostate Cancer?

Prostate cancer is a malignancy that develops in the prostate gland, a small walnut-shaped organ in men that produces seminal fluid. It is one of the most common cancers among men, often growing slowly and remaining confined to the gland initially, though aggressive forms can spread. Key facts include that early-stage prostate cancer may cause no symptoms, and screening via PSA blood tests and digital rectal exams is crucial for detection. Treatment options range from active surveillance for low-risk cases to surgery, radiation, and hormone therapy for more advanced disease.
