Classification of breast cancer:



Invasive Carcinoma - no special type (NST)




Grade 1 invasive carcinoma NST Grade 1 invasive carcinoma NST
Grade 1 Carcinoma NST: Low Power Left, High Power Right
Note frequent tubules, small nuclei and infrequent mitoses.


Grade 3 invasive carcinoma NST
Grade 3 invasive carcinoma NST Grade 3 invasive carcinoma NST
Grade 3 Carcinoma NST
Note sparse or absent tubule formatin, pleomorphic nuclei and frequent mitoses.
