My mother 64 is diagnosed with breast cancer. MRM done. Biopys says
INVASIVE DUCT CARCINOMA, NOS, GRADE III,pSTAGE : pT2N0.
AXILLARY : 16 LYMPHNODES ISOLATED, ALL ARE FREE OF TUMOR. (0/16)
Her tumor was tested (post surgery) for ER, PR and Her2-neu at Rajiv Gandhi, Delhi and the report said triple negative (HER2 as 0).
We took blocks for second opinion to Balaji Action, Delhi and the reports says ER-ve, PR-ve but HER2-neu as 2 to 3+ (equivocal).
Confused now as HER2 plays an decisive role in deciding the treatment.
is any of the lab above not 'standard'. what should we do next? experts pls suggest.
