Benign Sclerosing Papillary Lesion

I am a 43 year old with history of benign Fibroadenomas and unilateral serous nipple discharge.  It had been previously tested and come back negative on several occasions.  I also went for a ductogram in Jan & it came back ok. In July I developed a non lactating mastitis in the LB and went for a followup sonogram.  Infection had cleared, but the radiologist found what looked like a another fibroadenoma.  I went to the surgeon who recomended MRI & Core Needle Biopsy.  Radiologist results came back as fibroadenoma.  Pathology stated Benign Sclerosing Papillary Lesion.  I am scheduled next week for ductal lavage, excision and ductogram.  Can you give me some more info and an opinion?
Thank you so much!

Dear mel273:  Most of the time, papillary lesions are benign.  However, when these structures are identified, excision is recommended because there is a possibility that there could be malignant cells within the lesion (there is a risk that invasive papillary cancer could develop within an existing papilloma - although this is usually in cases where there are multiple papillomas) and a needle biopsy, which only takes a small sample, could lead to a false negative result.
