“DRE only forms part of the testing performed in the diagnosis of prostate cancer. The examination is not specific for prostate cancer and is used in combination with a blood test to check for prostate-specific antigen (PSA) level, a biomarker for prostate cancer, as well as a biopsy to check prostate tissue for the presence of cancer cells. ”
