    This is a malignant tumor. It is invasive ductal carcinoma/ tubular carcinoma. This tumor is Grade by by Nottingham grading system. Grade 1 tumors are mostly Luminal A type. Please take a look at the Molecular subtypes of Breast Carcinoma . If by IHC Her-2 neu is equivocal, Her-2 amplification study would be the next best step.
