prompt1 : extract information from  breast pathology report. List the histological classification, i.e. type of cancer or DCIS, subtype, description of any necrosis, any mention of tumor infiltrating lymphocytes,  histological grade, nuclear grade,  lymphovascular invasion, calcification, receptor status, IHC and any other ancillary testing results.  List out and expand the main points.
prompt2 : The report is - Subtype Her2, PATIENT HISTORY: Procedure Date: DATE OF LMP: DATE OF LAST DELIVERY: PRE-OP DIAGNOSIS: R BREAST CANCER. POST-OP DIAGNOSIS: SAME. OPERATTVEPROCEDURE: R'SEGM MAST; AXILLARY DISS. CLINICAL HISTORY: MATERIAL SUBMITTED: A) RIGHT SEGMENTAL MASTECTOMY, PROCUREMENT BY SURGICAL PROCEDURE. E) RIGHT AXILLA, PROCUREMENT BY SURGICAL PROCEDURE. INTRAOPERATIVE CONSULTATION: FROZEN SECTION: Right brcast mass, 2.1 by 2.1 by 2.0 cm, 0.4 cn from the closest posterior margin. FS. Diagnosis: Infiltzating ductal carcinoma. ER/PR taken. CONSULT: Right axillary y mph node dissection. Metastatic tumor in multiple matted Jymph nodes. FINAL DIAGNOSIS: FINAL DIAGNOSIS: A) RIGHT BREAST SEGMENTAL NASTECTOMY: - INFILTRATING DUCTAL CARCINOMA (2.1 CM), WITH EXTENSIVE LIMPHATIC PERMEATION AND CANCERIZATION OF THE. DUCTS, NUCLEAR GRADE POOR, HISTOLOGIC GRADE 3. - ALL SURGICAL RESECTION MARGINS FREE OF TUMOR. B) RIGHT AXILLA DISSECTION: - THIRTY FIVE OUT OF THIRTY NINE (35/39) LYMPH NODES, POSITIVE FOR METASTATIC INFILTRATING DUCTAL CARCINOMA,. SOME WITH EXTRACAPSULAR SPREAD. - PATHOLOGIC STAGING: T2 N2 MX.

expanded version (tokens=776) : 
 The breast pathology report provides the following information:

- Histological classification: Infiltrating ductal carcinoma, subtype HER2.
- Description of necrosis: Not mentioned in the report.
- Tumor infiltrating lymphocytes (TILs): Not mentioned in the report.
- Histological grade: Nuclear grade is poor and histologic grade is 3.
- Lymphovascular invasion: Extensive lymphatic permeation and cancerization of the ducts reported.
- Calcification: Not mentioned in the report.
- Receptor status: ER/PR status not specified in the report.
- IHC and other ancillary testing results: HER2 positive reported.

Expansion of main points:
The report shows that the patient had undergone a right segmental mastectomy along with right axillary dissection. The histological classification of the tumor was infiltrating ductal carcinoma, subtype HER2. The tumor was 2.1 cm in size with poor nuclear grade and a histologic grade of 3. The lymphovascular invasion was extensive, and all surgical resection margins were free of the tumor. The report mentions metastatic infiltrating ductal carcinoma in 35 out of 39 lymph nodes that were removed during the axillary dissection, some with extracapsular spread. The final diagnosis of the staging was T2 N2 MX.This report does not give any information on the hormonal or PR status of the cancer, only the HER2 status.

prompt : Please generate a succinct report in 75 words from the above information. Exclude any filler words or sentences. If something is not mentioned or specified, exclude it from the report. Low verbosity.

final output (tokens=918) : 
 Patient underwent a right segmental mastectomy with axillary dissection. Histological classification revealed a HER2-positive infiltrating ductal carcinoma, grade 3 nuclear grade. The cancer showed extensive lymphatic permeation but all surgical margins were free of tumour. Of the 39 lymph nodes removed, 35 had metastatic tumours with extracapsular spread - T2 N2 MX staging. No mention was made of PR or ER status in the report.
