Risks of Screening for Bladder and Other Urothelial Cancers
Key Points for This Section
Decisions about screening tests can be difficult. Not all screening tests are helpful and most have risks. Before having any screening test, you may want to discuss the test with your doctor. It is important to know the risks of the test and whether it has been proven to reduce the risk of dying from cancer.
Screening test results may appear to be abnormal even though no cancer is present. A false-positive test result (one that shows there is cancer when there really isn't) can cause anxiety and is usually followed by more tests (such as cystoscopy or other invasive procedures), which also have risks. False-positive results often occur with hematuria testing; blood in the urine is usually caused by conditions other than cancer.
Screening test results may appear to be normal even though bladder cancer is present. A person who receives a false-negative test result (one that shows there is no cancer when there really is) may delay seeking medical care even if there are symptoms.
Your doctor can advise you about your risk for bladder cancer and your need for screening tests.
