intermediate grade

(IN-ter-MEE-dee-ut grayd)
A term used to describe how abnormal cancer cells look under a microscope. Intermediate-grade cancer cells look more abnormal than low-grade cancer cells but not as abnormal as high-grade cancer cells. They also tend to grow and spread more quickly than low-grade cancer cells but not as quickly as high-grade cancer cells. Cancer cell grade, along with cancer type and stage, may be used to help plan treatment and determine prognosis.
