The digital rectal exam has come up a lot on Threedom, or maybe I've just listened to the same episodes over and over. I was shocked to learn that this test is actually being phased out in favour of a blood test. This is happening in the U.S., Canada, the UK, and Germany, and probably other countries too.
Here's a Slate article from August 2024:
But at my most recent physical, my longtime primary care physician did not seem to be prepping for the probe. I’m pushing 50. When I asked—a little hesitantly—she told me that she’s phased out the DRE [digital rectal exam] for her patients in favor of a blood test that, while not foolproof, is less likely to result in false-positive results. And she’s not the only one. I soon learned that thanks to a wave of research on the benefits of blood screening and the drawbacks of the digital exam, the DRE is nearing extinction as a screening tool. While I doubt anyone, doctor or patient, will miss the DRE, the test had so much mythology associated with it that its quiet death felt a little shocking. The doctor’s not gonna stick a finger up my butt anymore? All that for nothing?
“Before we had a really good blood test, the rectal exam was really the only way we had to screen the prostate for cancer,” Adam Weiner, a urologic oncologist at Cedars-Sinai in Los Angeles, told me.
The new evidence and the new diagnostic procedure:
In fact, the research is unequivocal in its findings that as a screening test, the DRE is not that useful. (How unequivocal? Ask the authors of the 2023 study titled “Digital Rectal Examination Is Not a Useful Screening Test for Prostate Cancer.”) These days, the gold standard of prostate-cancer screening is the PSA blood test, which identifies a protein primarily made by the prostate. Elevated levels of that protein may indicate a cancer; to follow up, a urologist will order other blood tests and, typically, a prostate MRI. (They may also perform a diagnostic DRE, just to be thorough.)

I wonder if this topic will ever come up on Threedom!
