Rectal examination has no advantage over the PSA blood test for prostate cancer screening. This has been shown by a study published in the journal. European Urology Oncology.
Common methods of prostate cancer screening include digital rectal exam and prostate-specific antigen (PSA) testing, whose high levels can indicate prostate cancer. But many men do not undergo rectal screening.
In the new study, researchers pooled and analyzed data from eight studies involving a total of 85,738 men. The results show that rectal exams alone or in combination with PSA testing do not help detect more cancer. Scientists believe that the possibility of excluding rectal examination from prostate cancer screening should be considered.
The authors concluded: “The reliability of rectal examination in detecting prostate cancer is not particularly impressive, suggesting that it is not necessary to routinely perform this examination as part of screening in the absence of clinical symptoms and signs.”
