What does differentiation mean?

You may notice the word “differentiation” on your pathology report. This refers to the grade of the cancer. In other words, it relates to how abnormal your cancer cells look under a microscope. Well-differentiated adenocarcinoma is considered low grade. This type of cancer tends to grow and spread slower. Poorly differentiated adenocarcinoma is considered high grade because it usually spreads faster.
