The U.S. Centers for Disease Control and Prevention (CDC) recommends that all non-emergency medical visits and procedures be postponed to allow doctors, hospitals and related services to focus on the COVID-19 outbreak. This includes tests or procedures sued to screen for cancer, such as a scheduled colonoscopy or an annual mammogram. However, diagnostic and staging procedures for cancer may be necessary, in some cases, especially if a patient has symptoms, such as bleeding or pain. Talk to your doctor about whether your screening or diagnostic procedure is necessary or can be rescheduled.
