Fluids made in the prostate gland mix with sperm to create semen, which are important both in reproduction and protecting the urinary tract and sperm from infections. When things go wrong in the prostate gland, problems with urination can occur. Learn More About The Prostate Gland In fact, many prostate cancers are believed to be slow growing, with men dying from causes other than prostate cancer. Autopsy studies support this, with one analysis of 19 different autopsy studies finding a high prevalence of undiagnosed prostate cancer in men as young as 30, and in more than half of men over age 80. (2) There are some factors that increase risk for prostate cancer, including: Race African-American men are far more likely to develop prostate cancer than white men — 203.5 vs. 121.9 cases per 100,000 men. They are also more than twice as likely as white men to die of prostate cancer — 44.1 vs. 19.1 deaths per 100,000 men. (3) Family History Positive family history of prostate cancer is another risk factor. Obesity Obesity is another risk factor linked to an increased risk of prostate cancer–specific mortality and biochemical recurrence in men with prostate cancer. (6)
PSA Screening for Prostate Cancer: A Controversial History
The history of the role of the prostate-specific antigen (PSA) test for prostate cancer is controversial. The prostate-specific antigen (PSA) blood test was created in the late 1980s, and tests for elevated levels of the antigen. Elevated levels can be suggestive of prostate cancer. The test itself is insufficient for diagnosing prostate cancer and was initially proposed as a marker of prostate cancer recurrence or disease progression. But doctors quickly began using it for cancer screening throughout the United States. Also, in the late 1980s, surgeons in the United States and Europe perfected the technique of radical prostatectomy, which involves removal of the prostate gland and any cancer within it. Initially, it seemed like an ideal situation: Men could have a simple blood test and prostate cancers that had not spread outside of the prostate gland could be cured. But as time wore on, problems emerged that had not been anticipated when PSA screening was introduced:
PSA could be raised by infections or other impacts on the prostate.Biopsies were needed to confirm the presence of cancer, but it was difficult to distinguish between those cancers that might be aggressive versus those that were slow growing. Many men with low-grade prostate cancers received unnecessarily aggressive intervention.Overdiagnosis became a concern. Men were getting treated for prostate cancer even though their cancers were very slow growing and not life-threatening.Overtreatment became an issue. Radical prostatectomy and radiation therapy often have side effects, such as urinary, sexual, and bowel problems. These were particularly problematic considering that many men with low-grade prostate cancer may not have needed them.Physicians became concerned that these impacts were potentially reducing men’s quality of life without helping extend their lives.
Current PSA Screening Recommendations
PSA-based screening refers to testing healthy men without symptoms. Until recently, physician societies disagreed on screening recommendations, but with the publication of the U.S. Preventive Services Task Force Guideline in May 2018, all the major physician groups are broadly in agreement, including the American College of Physicians (ACP), the American Cancer Society (ACS), American Urological Association (AUA), and American Society of Clinical Oncology (ASCO):
They advise supporting men so that they make informed decisions about screening that reflect their personal preferences and values.Routine screening is not recommended in men between ages 40 and 54 of average risk.For men ages 55 to 69 years, the U.S. Preventive Services Task Force concluded “with moderate certainty that the net benefit of PSA-based screening … is small for some men, making the decision up to the judgment of the physician and the values of the patient.”For men 70 years and older, they recommend against routine screening because the expected harms are thought to outweigh the benefits.Your doctor should not screen you unless you express a preference for it.A discussion of the benefits and harms of screening should include a family history of prostate cancer, race or ethnicity, any medical conditions that affect your overall health and lifespan, and your values about risk and benefit.If you have less than a 10-year life expectancy, screening is not recommended.
Should Men at Elevated Risk Be Screened More Aggressively?
It might sound logical to screen high-risk men earlier or urge men to adopt a healthy lifestyle to lower their risk for prostate cancer, but these areas have not been studied sufficiently. Therefore, physician organizations recommend more research and individualizing decisions about whether to get screened. Meanwhile, some leading organizations have issued recommendations, including:
The American Urological Association The AUA recommends individualizing decision-making for men younger than age 55 who are high risk because they are African-American or have a positive family history. (7)The U.S. Preventive Services Task Force The USPSTF largely agrees with AUA’s position and its 2018 recommendations are based on AUA’s evidence review.The American Cancer Society The ACS takes this a step further, urging discussion about screening begin earlier for African-American men and men with first-degree relatives who have had prostate cancer.
The stages are based on guidelines set by the American Joint Committee on Cancer (AJCC). To determine your prostate cancer stage, your doctor will perform a number of tests, including:
Digital rectal exam, in which your prostate is felt for abnormalitiesA blood test to measure the amount of PSA that’s circulating in your body (generally, PSA levels are higher for more advanced prostate cancers)A biopsy to extract cancerous tissue and grade how likely it will spread based on its appearance compared with normal prostate tissue (the grade is called the Gleason)Various imaging tests, such as computerized tomography (CT) and magnetic resonance imaging (MRI) scansBone scans to look for cancerous cells in bone

That is, they’ll keep an eye on the development of the tumor using various tools and tests, including:
Digital rectal examsPSA blood testsTransrectal ultrasoundsProstate biopsies
Men who require treatment for their condition are most often treated with surgery, radiation therapy, hormone therapy, chemotherapy, or a combination of these modalities.
