Abstract
Upon performing contact thermography on the patients with breast cancer, the thermograms obtained were classified into 3 types (hot spot: H, irregular vascular pattern: IV, and asymmetrical thermal pattern: AT). The following results have been obtained as a result of making an assessment regarding how the findings are reflected on the classification of clinically morbid periods.
1) Positive AT and IV findings were observed on the thermograms even in the breast cancers in comparatively early stages.
2) H findings showed that the positive rate became higher as tumorous diameter became larger and further that high positive rates were exhibited in scirrhus carcinoma.
3) In the relation with nuclear DNA amount, positive rates of H findings were high in aneuploid cases.
4) The change in thermography showed a positive correlation with the change in dermal blood stream.
From the above, it was found that the contact thermography has a nature a little different from the conventional test methods and that its usefulness was observed rather in the judgement on the malignancy of breast cancer cells but not as diagnostic test method. Further, a possibility of foreknowing the risk of breast cancer to occur was suggested.
