The term no evidence of disease (NED) is often used with cancer when there is no physical evidence of the disease on examination or imaging tests after treatment. No evidence of disease means the same thing as complete remission or complete response. It does not, however, mean that a cancer is cured. With most cancers, there is a chance it could recur at a later date.

Levels of Disease

The National Cancer Institute defines remission as a “decrease in or disappearance of signs and symptoms of cancer." Remission is further categorized as either partial remission (when only some of the signs and symptoms of disease have disappeared) or complete remission (when all are gone, but cancer may still remain).

The latter applies to NED. It describes a point in time when you have no signs or symptoms of cancer, nor any evidence of cancer on blood tests, such as tumor marker tests, or imaging studies, including computed tomography (CT), magnetic resonance imaging (MRI), bone scans, or positron emission tomography (PET). NED may be temporary, as cancer could still be lurking. But it could also be permanent.
