Lymphoscintigraphy cannot diagnose breast cancer.

Axillary lymphoscintigraphy was performed by the technique of Agwunobi and Boak (1) in 68 patients with operable cancer of the breast and 11 patients with benign disease. Contrary to their previous report, scans were found to be indistinguishable from normal in the majority of breast cancer patients with interpretable scans, and no pattern of uptake was found which was typical of carcinoma in the corresponding breast.
