In 1969-1970 a breast mass-screening was undertaken in Gävle, with thermography and questionnaire. Mammary radiography and clinical examination of subjects with abnormal screening reports and of a group of normal subjects were performed. In spite of having achieved early detection of malignant tumours in many cases with a preponderance of carcinoma cases in the abnormal group, thermography was found to have considerable drawbacks as a screening method.
