This proved at excision biopsy to be an intraduct papilloma.

These clinical indices of aggression include size of tumour, nodal metastases, high Bloom-Richardson histological grading, lymphovascular invasion and an extensive intraduct

This enables detection of small tumours, intraduct papillomas and some other benign changes.
