Standard Treatment for Probable Sclerosing Papilloma

So, following a sterotactic biopsy on Jan. 8 for a new tiny microcalcification found on a routine screening,the pathology report was not cancer but fragments of "probable sclerosing papilloma" and some atypical cells.  The doctors recommend lumpectomy.  The doctors also said that the papilloma may have a 1 to 3 % chance of being cancer or DCIS and that is why they want to remove everything around the marker left by the biopsy.  I am 55 years old and in otherwise good health, no surgeries or symptoms.  I feel I am being rushed into this.  Is lumpectomy standard for papillomas?  First, they had me nearly losing my mind over worry about microcalfications, now this!  If surgery is standard, how do I find a great breast surgeon?  I am really feeling overwhelmed by all of this and appreciate feedback.  Thank you!
