1. The role of post operative imaging in the management of close and positive DCIS margins was not mentioned. Does more imaging to determine obvious residual disease play a role in the decision to re-excise vs. boost radiation?	We have added a qualifying statement to Recommendation 1: The use of imaging modalities to assess for residual disease in patients with positive markings post BCS is outside the scope of this guideline but the Working Group consensus favors positive margins being treated surgically given perceived low sensitivity for detecting residual disease versus postoperative changes in patients having undergone recent surgery with all imaging modalities.
