title: Preoperative localization of nonpalpable breast tumours.
abstract: A simple method for the preoperative localization of nonpalpable breast tumours detected by mammography is described. A small amount of a mixture of contrast media and visible dye is injected into the breast precisely ventral to the lesion and the site of injection is marked on the skin. Forty patients have been operated upon and all the tumours were found without difficulty.
