Thermography in the follow‐up of breast cancer patients after breast‐conserving treatment by tumorectomy and radiation therapy

It is often suggested in the literature that thermography is able to diagnose a recurrence in the breast after breast‐conserving therapy by a rise in breast temperature much earlier than other diagnostic tools, but no thermographic values are presented. The thermographic data of a prospective study of 309 women after breast‐conserving therapy were evaluated. Seventeen of these women had an intramammary recurrence. A total of 2432 individual measured values were evaluated from 292 patients without evidence of a recurrence and 146 measured values from 17 patients with intramammary recurrence. The thermographic behavior of the breast after breast‐conserving therapy is not uniform. However, the breast temperatures of the patients with intramammary recurrences were not significantly different from those without recurrences. This means that thermography is of no value in the care after breast‐conserving therapy.
