In invasive lobular carcinoma of the breast (ILC), conventional imaging is unable to assess tumor size. Though preoperative MRI has been shown more reliable, the use of preoperative MRI is disputed. We assessed the need for surgical re-excision and the rate of mastectomies in patients treated for ILC with or without preoperative breast MRI. Our results clearly show that preoperative MRI reduces the rate of re-excisions without increasing the rate of mastectomies and should thus be performed in all patients.
