About the PSA screening test
The PSA test
PSA, or Prostate-Specific Antigen, is a protein produced by normal, as well as malignant, cells of the prostate gland. The blood level of PSA is often elevated in men with prostate cancer. However, PSA levels can also rise because of some some non-cancerous conditions, such as inflammation of the prostate and enlargement of the prostate. Most organizations recommend that men who are considering PSA screening first discuss the risks and benefits with their doctors.

"We encourage all men to have a conversation with their doctor about PSA screening"
The American Cancer Society’s 2022 Cancer Facts & Figures shows that death rates for cancer overall continue to decline for both men and women. However, the report also reveals that the death rate from prostate cancer is no longer declining as quickly, says Charles J. Ryan, MD, CEO of the Prostate Cancer Foundation (above).
“A main reason is that more men are being diagnosed at an advanced stage. For these patients, the 5-year survival rate is only 31%. Additionally, the disparities in prostate cancer incidence and death between Black and White men remain unacceptably high.”
“Survival from prostate cancer is significantly improved when caught early. Catching the disease early involves a conversation between a man and his doctor, as well as a physical exam and PSA testing. We encourage all men to have a conversation with their doctor about PSA screening and a conversation with their family about cancer history.”

Should you get your PSA level tested?
Knowing your PSA level can help determine your chance of having prostate cancer.
However, the PSA test can have negative consequences, as well. PSA levels are sometimes high when cancer isn’t present. And testing can’t always tell which prostate cancers are deadly and which ones won’t cause problems.

About the PSA test
“We use PSA in a few different ways to think about your risk for prostate cancer,” says Adam Feldman, MD, of the Massachusetts General Hospital Department of Urology.
“One is looking at it over time. So sometimes it’s elevated and if we just get one snapshot in time it may just be your baseline PSA. We also try and look at it in relation to your age and to the size of your prostate. We know that a larger prostate will make more PSA.”

Why Controversy over PSA test?
After years of widespread PSA screening, the U.S. Preventive Services Task Force in 2012 made the controversial decision not to recommend routine PSA testing on the grounds that too few lives are saved to justify all the harm that’s done treating healthy men.
Five years later in 2017, the Task Force changed its stance, recommending that the decision whether or not to do PSA screening should be made individually for each man aged 55 to 69. This new position has been criticized for not taking into account that African American men are more likely to be diagnosed at younger ages and with more aggressive tumors compared with White men.

"We don't have adequate screening data for African American men"
Despite the fact that African American men are much more likely to develop and die from prostate cancer as White men, “young African American men are poorly represented in PSA studies from which evidence-based guidelines are developed,” says Lori J. Pierce, MD, President of the American Society of Clinical Oncology.
“So, this really limits proper PSA guidance screening guidance for African American patients, especially for those who are younger than 55. And so, because we don’t have adequate screening data, there are differences in opinion as to what the guidelines should be.”
"We need more studies to know what's right for high-risk men"
“One of the problems we have with the science is thinking about high-risk men,” says Alex H. Krist, MD, Chair of U.S. Preventive Services Task Force. The Task Force has not made any specific recommendations about screening in African American men.
“So men who are African American or men who have a family history of prostate cancer? Does screening help them any more than an average-risk man? We also don’t know if they have greater harms from the whole screening process. We need more studies to know what’s right for high-risk men.”

American Cancer Society: Advances have lessened over-detection and over-treatment from PSA testing
“Controversy remains about the underutilized potential of the PSA test for reducing prostate cancer mortality by detecting potentially fatal disease earlier. The value of screening is especially salient for Black men, who have had a steeper drop in PSA testing than White men despite two-fold higher prostate cancer mortality.
Proponents of testing are bolstered by advances in mitigating over- detection and over-treatment through more stringent diagnostic criteria and active surveillance for low-risk disease.
In addition, promising new approaches to screening that include the use of molecular markers and magnetic resonance imaging-targeted biopsy have demonstrated success in the detection of clinically significant cancer with limited over-detection.”

New Research About Prostate Cancer Screening in Black Men
Opinions About Earlier Prostate Cancer Screening
"Black men should start PSA screening earlier"
“When we are discussing early-stage prostate cancer, there are no early warning signs or symptoms,” says radiation oncologist Jerome M. Butler, MD, of North Carolina.
“Given that we know that African American males have a higher risk of prostate cancer, we believe that prostate cancer screening cannot be ignored.
For asymptomatic men of average risk, prostate screening should begin at ages 55 to 69. We believe that African American males should start earlier.”

"Know your prostate health beginning at age 40"
“All Black men are at high risk for prostate cancer,” says Thomas Farrington, founder of the Prostate Health Education Network (PHEN) and a prostate cancer survivor.
“It is very important to know your prostate health. Knowledge is the best defense against prostate cancer. You begin that by knowing the health of your prostate.
So we recommend that men begin early detection testing to know their prostate health beginning at age 40 using a PSA test and the digital rectal exam. Because early detection is so crucial to beating this disease should you be diagnosed with it.”

Should Black men get their PSA levels checked?
Yes, says Richard Kennedy, MD, whose prostate cancer was discovered after a high PSA test.
“The dilemma is in people of color, we die at greater rates with prostate cancer, we tend to have more aggressive cancer at the time of diagnosis than other populations. So for us, it’s different. We tend to be always at the end of the scale. Prevention is the key,” says Kennedy.
“The one thing that has been proven over time is that most disease when it does affect people of color, it tends to be more aggressive. That’s probably happening more because we show up late. “
