Local recurrence occur in patients who were treated with breast-conserving surgery, and it is highly significant when there is stromal over growth (P value <0.01 and Chi square of 8.21) in comparison with the resection margin without stromal overgrowth (P value <0.1 and Chi square of 3.23) which gives a clue for further studies about the stromal factor role in recurrence of the tumor.
