But while the appeal of PSA screening is understandable, controversy began almost as soon as the PSA test became popular, as some experts worried that testing might do more harm than good. Although the arguments for and against PSA screening date back to the 1990s, the basic logic behind each position remains largely unchanged.
The PSA test is the leading method of screening for prostate cancer. PSA screening can help catch the disease at an early stage when treatment may be more effective and potentially have fewer side effects. The PSA test may be done along with a digital rectal exam (DRE), in which a physician inserts a gloved finger into the rectum to examine the
The screening can present abnormal results even when a man does not have cancer (known as a false-positive result), or normal results even when a man does have cancer (known as a false-negative result). After correcting for non-compliance and contamination, PSA screening led to 32.4 (95% CI 26.4, 38.6) more PC diagnoses per 1,000 men and 1.4 (95% CI 0.0, 2.8) fewer PC deaths compared to the control arm. These results can be used for patient counselling in informed decision-making about PC screening. Elevated PSA results may reveal prostate cancer that's likely to spread to other parts of your body (metastasize), or they may reveal a quick-growing cancer that's likely to cause other problems. Early treatment can help catch the cancer before it becomes life-threatening or causes serious symptoms. But PSA results aren’t always reliable, and sometimes doctors aren’t sure what they mean. Before starting treatment, you might want to ask your doctor what he or she expects your PSA level to be during and after treatment, and what levels might cause concern.
