Out of one hundred and sixty-two patients that examined by contact thermography, forty-five cases involving 55 cancers were assessed for malignancy. The sensitivity and the specificity of this method of testing were 81.5% and 83.5%, respectively. False negative cases included early stage, small sized and papillotubular carcinomas. Twenty-five per cent of the fibroadenoma and mastopathy cases showed false positive findings. Further, half of the phyllodes tumor and mastitis cases also showed false positive findings. Two of six T0, Tis cases (33.3%) were diagnosed as malignant tumors by thermography. Contact thermographic examinations will be more widely used in the near future.
