Screening for prostate cancer prostate-specific antigen (PSA) tests is again put under the microscope as the Philadelphia Inquirer reports why more health care providers are having second thoughts. There are about 180,000 new cases of prostate cancer diagnosed each year. Yet, “the PSA test can’t tell which cancers are aggressive. Moreover, there is no ‘normal’ level of the antigen, which is shed by the gland. Studies have found that many men with low levels have cancer, while many with modestly elevated levels—enough to warrant a biopsy—do not.”
Case closed? Well, not necessarily. The newspaper ran a companion piece to the story that details how early PSA screening saved one man’s life.
