[Infrared light scanning in differentiating benign and malignant breast diseases].

One hundred and fifty patients with various breast diseases were studied using infrared light scanning. The results were compared with those of X-ray mammography and BUS. In 42 cases of breast cancer, 97% were correctly diagnosed using infrared light scanning. The method was significantly superior to X-ray (60%) and BUS (83%). To detect benign diseases, including adenofibromas (30 cases) and hyperplasias (21 cases), infrared light scanning was useful in this series in contrast to X-ray and BUS.
