Mammographic density has an impact on the risk for re-excision after breast conserving surgery of primary breast cancer

Objective: Aim of our study was to evaluate the impact of mammographic density on the risk for a re-excision. Introduction: Positive tumor margins are critical concerning the local control after a surgery for breast cancer. Several factors like tumor size, multifocality and the presence of an extensive in situ component could be associated with a higher rate of second surgeries due to positive margins. Patients and Methods: 565 breast cancer patients were considered to be suitable for breast conserving therapy after a core biopsy has proven malignancy. Mammography of those patients was reviewed and mammographic…
