Remission (medicine)

Remission is either the reduction or disappearance of the signs and symptoms of a disease. The term may also be used to refer to the period during which this reduction occurs. A remission may be considered a partial remission or a complete remission. Each disease, type of disorder, or clinical trial can have its own definition of a partial remission. For example, a partial remission for cancer may be defined as a 50% or greater reduction in the measurable parameters of tumor growth as may be found on physical examination, radiologic study, or by biomarker levels from a blood or urine test.
