Q

Grade:For most cancers, the grade is a measure of how abnormal the cancer cells look under the microscope. This is called_____. Grade can be important because cancers with more abnormal-looking cells tend to grow and spread _____.

The grade is usually assigned a number. In _____-_____ (well-differentiated) cancers, the cancer cells look a lot like cells from normal tissue. In general, these cancers tend to grow slowly. In high-grade (_____ differentiated) cancers, the cancer cells look very different from normal cells. High-grade cancers often tend to grow _____ and have a worse outlook, so they may need different treatments than low-grade cancers. Even when the grade doesn’t affect a cancer’s stage, it may still affect the outlook and/or treatment.

Grade 0 is in situ or pre-cancerous or at a very early

A

differentiation
faster

low-grade
poorly
quickly
