If you are an elderly man, you may wonder if you should continue to have an annual PSA test to screen for prostate cancer. Here are the latest guidelines.
The U. S. Preventive Services Task Force recently recommended that doctors not screen men age 75 and older for prostate cancer. The panel weighed the potential benefits and harms of PSA testing in this population and concluded that the screening was more likely to have a negative impact on these men than a positive one.
The rationale: Prostate cancer is a slow-growing malignancy that may take 10 or more years to produce significant symptoms. Many elderly men will die of another condition before their prostate cancer becomes life threatening. Thus, an abnormal PSA test would lead to the pain and discomfort of a prostate biopsy and unnecessary worry if no cancer is found. If cancer is found and treated, the man will have to contend with side effects, such as sexual dysfunction and incontinence.
Other medical organizations recommend annual screening for men at average risk for prostate cancer beginning at age 50, but they do not address when screening is no longer necessary. And still others recommend screening for all men with a life expectancy of at least 10 years.
Bottom line advice: If you are age 75 or older, discuss the risks and benefits of PSA testing with your doctor. If you get tested and are diagnosed with a low-grade cancer, keep in mind that active surveillance is an option that allows you to be closely monitored but treated only if your disease progresses.
