I had ultrasound trucut biopsy of breast & histopath report showed papillary neoplasm with calponin & p63 stains negative. do i have breast cancer?

No enough info.: Papillary neoplasms of the breast can be benign or malignant. When found, these lesions need to be excised both to fully evaluate whether cancer is present and if not, to prevent cancer from forming as they can be pre-malignant. If breast cancer if present, papillary breast cancers usually have a very good prognosis.

Not necessarily,: because papillary neoplasms can be benign or malignant. The lesion needs to be surgically removed for a definitive diagnosis.
