Many doctors still give their patients who are 75 and older prostate-specific antigen tests for prostate cancer, even though many medical groups have recommended against it. A research letter published in the Journal of the American Medical Association on Oct. 16 reveals that about 41 percent of men in that age group had the PSA procedure done — and 29 percent had been recommended for the test by their primary care physician. “Our results suggest that a major reason for the continued high PSA rate is decision-making by the physicians,” said senior author Dr. James Goodwin, director of UTMB's Sealy Center on Aging. Lead author Dr. Elizabeth Jaramillo said that overtesting can create harms, including overdiagnosis. “The vast majority of prostate cancers are so slow growing that an elderly man is much more likely to die of another condition in his lifetime than from the cancer,” she said.
