Because no one should face breast cancer alone.

Grade

Printer-friendly versionSend to friend

Pathologists use a scale known as the Bloom-Richardson or Scarff-Bloom-Richardson scale to assign a histologic grade to the tumor.  As stated earlier, this score combines information about three factors that influence the growth rate of the cancer cells and describes the extent to which the cells resemble, or have ceased to resemble, normal breast cells in their appearance and behavior.  The tumor is classified as: 
 

Grade 1, or well-differentiated

Grade 2, or moderately differentiated

Grade 3, or poorly differentiated
 

Lower grade cancers are generally less aggressive, though this is not always true.  Be careful not to confuse grade with stage.
