The common treatment for<unk>  is wide local excision. Other than surgery, there is no cure for<unk> , as chemotherapy and radiation therapy are not effective. The risk of developing local recurrence or metastases is related to the histologic grade, according to the above-named features. Despite wide excision, a very high percentage of surgeries yielded incomplete excision margins that required revision surgery. Radiation treatment after breast-conserving surgery with negative margins may significantly reduce the local recurrence rate for borderline and malignant<unk> s. The authors of a 2012 study have derived a risk calculator for relapse risk of<unk> s after surgery.
