Causes

of Prostate Cancer Prostate cancer is a malignant tumor commonly found in men. It is the second most deadly type of cancer in the United States, after lung cancer. The primary cause of prostate cancer is unknown, but a number of risk factors have been identified including age, family history, ethnicity and lifestyle. Other possible causes include diet, environment, genetics and hormones. Early diagnosis and treatment are key in helping to reduce the risk of progression, making it important to detect prostate cancer early. Tests such as a digital rectal exam, prostate-specific antigen (PSA) test, transrectal ultrasound or biopsy may be used to help diagnose it. While treatments are available, they can have serious side effects, making prevention increasingly important. Healthy lifestyle choices and regular screenings are recommended to help reduce the risk of developing prostate cancer.
