To arrive at a diagnosis FNAC biopsy report is more important. As per the fnac report - left breast suggestive of proliferative breast disease
without atypia. On clinical examination, scan and mammography
there is a fairly defined small lump in the upper outer quadrant of left breast without lymphadenopathy
. Clinical diagnosis was Fibroadenosis
. Even though the chance for turning into malignancy is less without Atypia (Fine distinctions among levels of hyperplasia
and atypia, not significantly distinguish risk among patients). It is better to remove tumour in total and send for HPE. Further treatment depends as per second HPE report.
