There are two main screening tools that are used to detect prostate cancer.
- Digital Rectal Exam (DRE) - The doctor inserts a lubricated, gloved finger into the rectum and feels the prostate through the rectal wall. The prostate is checked for hard or lumpy areas.
- Prostate-specific Antigen (PSA) - A lab checks the level of PSA in a blood sample. The prostate makes PSA. A high PSA level is commonly caused by Benign prostatic hyperplasia (BPH) or prostatitis (inflammation of the prostate). Prostate cancer may also cause a high PSA level.
An abnormal test result may not mean you have prostate cancer. If either test result is abnormal, your doctor may recommend other tests to make a diagnosis.
