How do I know which screening test is right for me?

A: Scientific data do not currently suggest that there is one "best test." Each test has advantages and disadvantages. Patients and their doctors are encouraged to discuss the benefits and potential risks associated with each screening option as they decide which test to use and how often the patient should be tested. The Centers for Disease Control and Prevention (CDC) recommends that patients speak with their doctors about getting screened. Which test to use will depend on a patient's preferences, his or her medical condition, the likelihood the patient will follow up and have the test, and resources available for testing and follow-up.
