Is a Digital Rectal Exam Still Needed for Prostate Screening?

Prostate health is one of the most important parts of men’s health, but it is also one of the most commonly delayed. Many men avoid discussing prostate screening because they worry that the first step will automatically be a rectal exam.

The good news is that prostate screening today usually begins with a conversation about your risk and, in many cases, a simple blood test called a PSA test.

A digital rectal exam, also called a DRE, can still be useful, but it is not always the only or first test used for prostate screening. At Central Medical Centre, we want men to feel comfortable getting checked early. If you are hesitant about a rectal exam, there are still ways to begin assessing your prostate health, including PSA testing and ultrasound assessment.

What is a digital rectal exam?

A digital rectal exam is a short clinical examination where a doctor gently feels the prostate through the rectum. Because the prostate sits just in front of the rectum, this exam can sometimes help detect a prostate that feels enlarged, hard, irregular, or suspicious.

For some men, especially those with symptoms or abnormal test results, a DRE may still provide useful information. However, it is not the only way to start the conversation about prostate health.

Is the rectal exam still needed?

The answer is: sometimes.

The American Cancer Society states that men who choose screening should have a PSA blood test, and that a digital rectal exam may also be done as part of screening. Screening discussions are advised from age 50 for average-risk men, age 45 for higher-risk men, and age 40 for men at even higher risk.

What is a PSA test?

PSA stands for prostate-specific antigen. It is a protein made by the prostate gland and measured through a blood test.

A raised PSA does not automatically mean cancer. PSA can also increase because of benign prostate enlargement, inflammation, infection, recent ejaculation, urinary retention, or recent prostate manipulation. However, an abnormal PSA can help identify men who may need closer follow-up, repeat testing, imaging, or specialist review.

The U.S. Preventive Services Task Force notes that PSA-based screening for men aged 55 to 69 should be an individual decision made after discussing potential benefits and harms with a clinician. It also recommends against routine PSA-based screening for men aged 70 and older.

Can ultrasound replace the rectal exam?

Ultrasound can be very helpful, but it does not fully replace PSA testing or medical assessment for prostate cancer screening.

At Central Medical Centre, ultrasound can help assess:

• Prostate size
• Prostate enlargement
• Bladder wall changes
• Post-void residual urine
• Urinary retention
• Possible effects of an enlarged prostate on the bladder

This is especially useful for men with urinary symptoms such as poor stream, frequent urination, waking at night to pass urine, urgency, or incomplete bladder emptying.

However, an abdominal ultrasound mainly helps answer the question: “Is the prostate enlarged and affecting urination?” It does not reliably rule out prostate cancer by itself. PSA testing and clinical assessment remain important parts of prostate screening.

What if I do not want a rectal exam?

We understand.

Some men feel anxious, embarrassed, or uncomfortable about the idea of a rectal exam. That should not stop you from taking care of your health.

At Central Medical Centre, we really want you to live healthy. If you would prefer not to start with a rectal exam, you can still begin with a men’s health assessment, PSA blood testing, and ultrasound to help determine the size and health of your prostate.

If your PSA, symptoms, family history, or ultrasound findings suggest that further assessment is needed, your doctor can then discuss the next best step with you.

Who should discuss prostate screening?

Screening is not one-size-fits-all. The best time to start depends on age, family history, race, symptoms, general health, and personal preference.

The American Cancer Society recommends discussing prostate screening at:

• Age 50 for men at average risk who are expected to live at least 10 more years
• Age 45 for men at higher risk, including Black men and men with a father or brother diagnosed with prostate cancer before age 65
• Age 40 for men at even higher risk, such as those with more than one first-degree relative diagnosed at an early age

How often should PSA testing be repeated?

Follow-up depends on your PSA result and overall risk.

The American Cancer Society notes that men with a PSA below 2.5 ng/mL may only need retesting every 2 years, while men with a PSA of 2.5 ng/mL or higher may need yearly screening.

Your doctor may recommend a different interval depending on symptoms, previous results, family history, and overall clinical picture.

Symptoms you should not ignore

Do not wait for routine screening if you have symptoms. Book a medical review if you notice:

• Difficulty starting urination
• Weak urine stream
• Frequent urination
• Waking often at night to urinate
• Blood in the urine
• Blood in semen
• Pelvic discomfort
• Lower back or bone pain
• Unexplained weight loss
• New erectile or ejaculation problems

Many prostate symptoms are caused by benign enlargement or infection, not cancer. But symptoms should still be assessed properly.
