final output (tokens=2359) : 
 The left breast mastectomy specimen shows non-proliferative fibrocystic change and no malignancy. Invasive ductal carcinoma is present in the right breast mastectomy specimen, with ductal carcinoma in situ (DCIS) of the comedo subtype and nuclear grade 3 with necrosis. The tumor is estrogen receptor positive, progesterone receptor negative, and HER2/neu overexpressed with 3+ membranous staining. Surgical margins for both specimens are negative for any tumor cells.
