Accuracy of screening methods for the diagnosis of breast disease.
Clinical examination, thermography, and 70-mm. mammography were performed in 891 patients-414 presented to hospital with symptoms of breast disease and 477 were asymptomatic. Comparison of the diagnostic accuracy of these methods showed that neither thermography nor 70-mm. mammography has a useful place as an isolated screening procedure for breast cancer. In fact, we consider such a policy dangerous.
