Evaluation of Oncological Safety of Fat Grafting After Breast-Conserving Therapy: A Prospective Study.

Introduction: Breast-conserving treatment (BCT) consisting of a lumpectomy followed by radiation is considered the standard of care in early-stage breast cancer, and breast reconstruction using fat transfer has become the standard of care in these patients. Immediately following BCT, patients are theoretically the most prone for cancer recurrence caused by the remaining mass of glandular tissue. Therefore, we conducted a prospective study to evaluate the oncological safety of fat grafting in patients after BCT.
