The most common type of cancer in men is prostate cancer. It primarily affects the prostate gland, which is located below the bladder and surrounds the urethra. Prostate cancer typically occurs in older men, and its risk factors include age, family history, ethnicity, and certain genetic mutations. Symptoms may include urinary difficulties, blood in urine, or pelvic discomfort, but many men may not experience symptoms in the early stages. Regular screening, including prostate-specific antigen (PSA) tests, can help detect the cancer early. Treatment options vary and can include surgery, radiation therapy, hormone therapy, or active surveillance.
