The evolving role of the dynamic thermal analysis in the early detection of breast cancer

Abstract

It is now recognised that the breast exhibits a circadian rhythm which reflects its physiology. There is increasing evidence that rhythms associated with malignant cells proliferation are largely non-circadian and that a circadian to ultradian shift may be a general correlation to neoplasia.Cancer development appears to generate its own thermal signatures and the complexity of these signatures may be a reflection of its degree of development.The limitations of mammography as a screening modality especially in young women with dense breasts necessitated the development of novel and more effective screening strategies with a high sensitivity and specificity. Dynamic thermal analysis of the breast is a safe, non invasive approach that seems to be sensitive for the early detection of breast cancer.This article focuses on dynamic thermal analysis as an evolving method in breast cancer detection in pre-menopausal women with dense breast tissue. Prospective multi-centre trials are required to validate this promising modality in screening.The issue of false positives require further investigation using molecular genetic markers of malignancy and novel techniques such as mammary ductoscopy.
