Pathological grading standards.

Grade	The symptom manifestations
1^st grade	The infiltrating cells did not change or only a few cells did, and the total number of cells remained the same.
2^nd grade	The amount of invasive cancer cells reduced somewhat, but the total amount of cancer cells remained high, with a reduction of no more than 30%.
3^rd grade	Between 30% and 90% fewer cancer cells were seen.
4^th grade	More than 90% of the cancer cells were eliminated, leaving only a few small clusters and solitary cells.
5^th grade	The main tumor bed lacked infiltrating cancer cells, yet there may be mammary carcinoma in situ..
