Aim: To determine recurrence rate of carcinoma breast after mastectomy in our population and to determine various risk factors associated with local recurrence which would help in management of new carcinoma breast patients in future.

Methods: It was a descriptive study conducted on patients of carcinoma breast with stage II and III undergoing modified radical mastectomy with negative resection margins at Gulab Devi Hospital, Lahore. Total of 59 patients were recruited in study using purposive sampling technique.

Results: Mean age was 51.61±11.52 years with range from 26 to 78 year. Female 58(98.31%) predominated over the 1(1.69%) male. Recurrence rate was seen only in 5 (8.47%) female patients

Conclusion: Proper surgical technique results in less chances of carcinoma breast recurrence. Menopause, positive axillary lymphnodes, lymphovascular invasion and necrosis on histology are associated factors of recurrence.
