Prostate Cancer Diagnoses are Improving—But Rates Might Double to 2.9 Million by 2040

Prostate cancer is a growing concern worldwide, with cases projected to double from 1.4 to 2.9 million worldwide by 2040¹. Our aging population drives this alarming trend, and if left unchecked, could lead to a significant rise in prostate cancer-related deaths. 

But there’s hope on the horizon. Thanks to advancements in diagnostic tools, we’re now able to catch this disease earlier and more accurately than ever before, offering men a better chance of beating the odds.

Understanding the Prostate: A Key to Better Diagnosis

The prostate is a small gland located that is beneath the bladder, plays a critical role in male reproductive health. It doubles in size during puberty and continues to grow as men age, often leading to a condition known as benign prostatic hyperplasia (BPH). 

While BPH is non-cancerous (ref), it’s important to note that prostate cancer is a separate and much more severe issue.

Prostate cancer can develop at any age, but it becomes more common as men grow older. The majority of these cancers are slow-growing and may not pose an immediate threat. However, some cases are aggressive and can be lethal if not detected early. 

The challenge lies in distinguishing between these indolent and aggressive forms, a task that has long been difficult.

The Evolution of Prostate Cancer Screening

Historically, prostate cancer screening has been a mixed bag. The first widely used method was a rectal exam, which involved a doctor manually checking the prostate for abnormalities. However, this method proved to be less effective in detecting significant cancers.

The introduction of the PSA (prostate-specific antigen) test in the 1990s marked a turning point (ref). PSA is a protein produced by the prostate, and elevated levels in the blood can indicate the presence of cancer. 

While the PSA test led to a rise in early diagnoses, it also had downsides. Elevated PSA levels can be caused by benignconditions like BPH, leading to false positives and unnecessary biopsies.

This overdiagnosis and overtreatment eventually led to a backlash against PSA testing. In 2012, a prominent U.S. panel recommended against routine PSA screening (ref), and other countries followed suit. However, new research has since shown that repeated PSA testing, rather than a one-off test, can significantly reduce prostate cancer mortality (ref).

The Rise of New Diagnostic Tools

Today, the landscape of prostate cancer diagnosis is changing once again. Advances in MRI technology now allow for more accurate detection of prostate cancer, reducing the need for unnecessary biopsies (ref)

If a PSA test reveals elevated levels, doctors can use an MRI scan to pinpoint suspicious areas in the prostate, leading to more targeted and effective biopsies.

Another promising development is the use of active surveillance for men diagnosed with low-risk prostate cancer.Instead of rushing into surgery or radiation, these patients are monitored regularly to ensure their cancer isn’t progressing, reducing the risk of overtreatment.

Genetic Testing & AI: The Future of Prostate Cancer Diagnosis

Genetic testing is also poised to revolutionize prostate cancer screening. Researchers are developing tests that can identify men at high risk for aggressive prostate cancer based on their genetic makeup. 

A recent trial in the UK used a saliva test to screen for genetic mutations linked to prostate cancer, with promising results (ref).

Meanwhile, artificial intelligence (AI) is making waves in the field of pathology. AI systems are being trained to interpret MRI scans accurately, potentially outperforming human pathologists (ref). This could lead to even earlier and more precise diagnoses in the near future.

Making an Informed Choice

With these advances, the decision to undergo prostate cancer screening is becoming clearer. Regular PSA testing, combined with MRI scans and possibly genetic testing, can help men catch prostate cancer early and choose the most appropriate treatment.

Thanks to these innovations, let’s hope all men can grow old with, rather than die from, prostate cancer.
