GREAT BAY--For many men, agreeing to a prostate-specific antigen, or PSA, blood test is the hardest part. Then the result comes back higher than expected and a new worry begins: does this mean prostate cancer? The answer is no. A high PSA is a reason to investigate further, not a cancer diagnosis. An enlarged prostate, inflammation or infection can raise PSA, while recent ejaculation, cycling and some medical procedures can also temporarily affect the result.
PSA is a protein made by cells in the prostate, including normal and cancerous cells. That is why the test can be useful but cannot, by itself, tell a man whether cancer is present. The National Cancer Institute says that when an abnormal PSA is found during screening, a doctor may recommend repeating the test in six to eight weeks before deciding what should happen next. The aim is to see whether the elevation persists or may have been temporary.
What happens after a high result depends on more than one number. A doctor may consider age, previous PSA results, family history, symptoms, overall health, medications and other risk factors. The American Cancer Society notes that there is no single PSA cutoff that can say with certainty whether a man does or does not have prostate cancer. Many doctors consider a PSA of 4 nanograms per milliliter or higher a reason for further evaluation, while some use lower thresholds.
If the PSA remains elevated, the next step may include a digital rectal examination, commonly called a DRE. During this examination, the doctor checks the prostate for hard areas, lumps or other changes. A man may also be referred to a urologist, a doctor who specializes in the urinary system and male reproductive organs. This referral does not mean cancer has been found. It means a specialist will help decide whether more testing is appropriate.
Doctors now have several tools that can provide more information before a biopsy is considered. Additional blood or urine tests may be used to estimate the likelihood that significant prostate cancer is present. In some cases, a doctor may look at the percentage of PSA that circulates freely in the blood, known as percent-free PSA. Other tests, including the Prostate Health Index and 4Kscore, may also be considered depending on availability and the patient's circumstances.
An MRI of the prostate has also become an important part of the evaluation for many men. A multiparametric MRI can produce detailed images of the prostate and help identify suspicious areas. The scan can help doctors decide whether a biopsy is needed and, if one is performed, help target areas that deserve closer attention. An MRI can reduce uncertainty, but it cannot provide the final diagnosis on its own.
If PSA results, examination, imaging and other tests raise enough concern, a prostate biopsy may be recommended. During a biopsy, small samples of prostate tissue are removed and examined under a microscope. The American Cancer Society says a biopsy is the test that can confirm whether prostate cancer is present. Biopsies may be performed through the rectum or through the skin between the scrotum and anus, with imaging used to guide the doctor.
Reaching the biopsy stage still does not mean cancer is inevitable. Some biopsies find no cancer. Others identify cancers that are low grade and may not require immediate treatment. If cancer is found, the biopsy provides information about how abnormal the cells look and how likely the cancer may be to grow or spread. That information, together with PSA and imaging findings, helps doctors decide what should happen next.
Men should also tell their doctor about anything that could have affected the PSA result. Pain or burning during urination, fever, difficulty urinating or pelvic discomfort may point to infection or inflammation that needs medical attention. Recent procedures and all medications should also be mentioned. Certain drugs used to treat an enlarged prostate can lower PSA levels, another reason the number should be interpreted by a healthcare professional rather than viewed alone.
For men in St. Maarten and across the Caribbean, the biggest mistake after an elevated PSA may be failing to follow up. Fear can make it tempting to avoid the next appointment, but an abnormal result needs an explanation. It may be caused by something benign, or it may lead to the detection of cancer at a stage when there are more options for management and treatment.
If your PSA comes back high, ask clear questions: Should the test be repeated? Could an enlarged prostate or infection explain the result? Do I need to see a urologist? Would an MRI or another test help? At what point would you recommend a biopsy? The goal is not to panic over a number. The goal is to understand what the number means for you and complete the follow-up needed to get an answer.
