cancer screening tests
Screening — checking a seemingly healthy person for signs of hidden disease — is an important part of routine medical care. It is done for various types of cancer, heart disease, diabetes, and other chronic conditions. Screening makes sense when finding and treating a hidden condition will prevent premature death or burdensome symptoms. But it doesn’t make sense when it can’t do either. That’s why experts recommend stopping screening in older individuals, especially those who aren’t likely to live another five or 10 years. Yet an article published online in JAMA Internal Medicine shows that many doctors still recommend cancer screening tests for their older patients. Many don’t benefit, and some are even harmed by the practice. Asking people who can’t benefit from a cancer screening test to have one is a waste of their time and money, not to mention a waste of taxpayer money (since these tests are usually covered by Medicare). Screening tests can also cause physical and mental harm. Decisions about cancer screening should be mutually made by an individual and his or her doctor. Equally important, the person should be well informed about the risks of the test and about what will happen if a test suggests there may be cancer that won’t shorten the his or her life.
