A Comparative Analysis of Lobular and Ductal Carcinoma of the Breast: Presentation, Treatment, and Outcomes1 1This study was supported by the American Cancer Society and the American College of Surgeons.

Abstract

Invasive lobular carcinoma presents with a similar age distribution, anatomic subsite, diameter, and grade as invasive ductal carcinoma. Breast preservation is selected less commonly for women who have invasive lobular carcinoma, but this choice of therapy does not compromise the disease-free or overall survival status of this group of patients.
