They are different things.
The grade refers to the how much the cancer cells look like normal cells. Grade 1, also called well-differentiated, look like normal cells and aren't considered aggressive.They grow slowly and metastesize slowly. Grade 3, also called poorly differentiated, are more likely to grow faster and to metastesize.
The system most often used to describe the growth and spread of breast cancer is the TNM staging system. Information about the tumor, nearby lymph nodes, and distant organ metasteses is combined, and a stage from I to IV is assigned.
A cancer's grade along with its stage is used to determine treatment.
