ER: estrogen receptor, HER2: human epidermal receptor, NCB: needle core biopsy, NOS: not otherwise specified, PR: progesterone receptor, TNM: tumor, nodal, metastasis. Well differentiation cancer refers to cancer cell that look like normal cell whereas moderate differentiation somehow look like normal cell. The more the similarity of cancer cell appearance to the healthy one, the lower the tumor grade is. Tumors with low grade are associated with less aggressive prognosis
