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.
