In combination with X-ray mammography and clinical examination thermography adds to the accuracy of breast cancer diagnosis. Thermographic examinations can be repeated at short intervals with no radiation hazard to the patient. However, performing and interpreting thermograms requires meticulous training. It was found that women with an abnormal thermogram are at a higher risk and have a poorer prognosis. A change in the thermal pattern is often the earliest sign of a cancer. The authors believe that the fault lies in misinterpretation of the thermogram, rather than the thermogram itself. Computer stimulations could be an adjunct tool to help the clinician in the interpretation.
