Popis: 4621 completely asymptomatic women underwent thermographic screening followed by clinical examination for breast cancer. 628 of the women were found to have abnormal thermograms and were referred for mammography. Of these 326 were abnormal but negative for malignancy 198 were negative 42 were positive for malignancy and 62 were suspicious of malignancy. Of the 62 9 were found positive at repeat roentgenogram indicating that thermography may indicate a malignant change at a time when the lesion is too small to be demonstrated radiographically. A positive thermogram should be considered as an indication for further study rather than biopsy. The false negative rate was 1.7 per 1000 women screened. Advantages of thermography are: 1) it provides simplicity of performance and repetition with no radiation hazard 2) it can provide an indication for further examination and 3) all women have nondeviating thermographic patterns except for older women who become progressively less vascular. Disadvantages include: 1) the "coldness" of scirrhous cancer 2) bilateral cancers may be interpreted as negative 3) there is no spatial relationship to the cancer and 4) thermographic signs of cancer occur in benign conditions.
