Prediction tool helps estimate local recurrence in patients with noninvasive breast cancer
The decision regarding treatment following breast-conserving surgery for patients diagnosed with ductal carcinoma in-situ (DCIS) has long been an area of discussion and confusion for patients and physicians alike.

While both treatments have been proven to lower the risk of recurrence in the breast, neither has been shown to improve survival, and both carry potentially serious risks. In an attempt to help physicians and patients weigh the risks and benefits of the available options, researchers from Memorial Sloan-Kettering Cancer Center (MSKCC) are reporting in the Journal of Clinical Oncology on the development of a new prediction tool that calculates a patient's individualized risk for recurrence five and ten years after surgery.
