Background: Breast cancer is the commonest malignancy in women and comprises 18% of all female cancers. The goal of modern breast surgery is to cure patients with preservation and reconstruction of breast tissue leading to satisfactory physical and psychological outcome. Aim of the Work: to evaluate modification of Dougnut technique in reduction mamoplasty as part of oncoplastic breast surgery for breast cancer. Patients and Methods: This prospective study included 20 female patients diagnosed with breast cancer suitable for management with the modified doughnut breast oncoplastic reduction mammoplasty surgery the age of the patients varied from 22 and 60 years old. The mean age for our study was 46.5. Results: From the 20 patients, the most common were of cup size C and D with the later being the mean and accounting for more than half (55%). The mean tumor size was 3.37  1.01 with a mean distance from NAC of 2.86  0.85. The location was 60% paraaereolar and 40% in the lower half of the breast. 13 (65%) patients underwent operation unilateral and 7 (35%) patients underwent bilaterally. The most common tumor pathology was IDC (70%). Regarding our patients' cosmetic satisfaction, the overall mean score of our study was 4.35 which falls between very good and excellent Conclusion: The modification of oncoplastic surgical techniques allows combining of several benefits, as here the modified doughnut technique benefiting from combining the round block and superior medial techniques giving better access of tumors and oncological control around the breast and reduction mammoplasty in large breast of cup C, D and more, with safe NAC and good aesthetic outcome. That technique showed good adoption bilaterally which is a key for
symmetrization in oncoplastic surgeries.
