Breast Thermography – The Mammography Alternative?
Center for Medical Consumers - April 2012
What happens when a popular cancer screening technology is found to be far more harmful than lifesaving? When the finding becomes clear decades after it was oversold to the public? When a lucrative industry, in terms of equipment, breast biopsies, drugs, etc., has already built around it that is now impossible to dismantle? In his new book Mammography Screening: Truth, Lies and Controversy (Radcliffe Publishing, London/New York: 2012), physician and research scientist, Peter C. GÃ¸tzsche recounts what it was like to take a hard look at that research and find it didn’t match up with mammography’s sterling reputation.
Some Selected Research:
Stark. A., Way, S. The Screening of Well Women for the Early Detection of Breast Cancer Using Clinical Examination with Thermography and Mammography. Cancer 33: 1671-1679, 1974
Researchers screened 4,621 asymptomatic women, 35% whom were under age 35 y.o. and detected 24 cancers (7.6 per 1000) with a sensitivity and specificity of 98.3% and 93.5% respectively

AJR:180, January 2003 Compared results of Infrared imaging prior to biopsy. The researchers determined that Thermography offers a safe, noninvasive procedure that would be valuable as an adjunct to mammography in determining whether a lesion is benign or malignant with a 99% predictive value.
Gros, C, Gautherie, M. Breast Thermography and Cancer Risk Prediction. Cancer 45:51-56 1980 From a patient base of 58,000 women screened with thermography, researchers followed 1,527 patients with initially healthy breasts and abnormal thermograms for 12 years. Of this group, 40% developed malignancies within 5 years. The study concluded that "an abnormal thermogram is the single most important marker of high risk for the future development of breast cancer"
Spitalier, H., Giraud, D. et al. Does Infrared Thermography Truly Have a Role in Present Day Breast Cancer Management? Biomedical Thermology pp.269-278, 1982
Spitalier and associates screened 61,000 women using thermography over a 10 year period. The false negative and positive rate was found to be 11% (89% sensitivity and specificity). 91% of the nonpalpable cancers (T0 rating) were detected by thermography. Of all the patients with cancer, thermography alone was the first alarm in 60% of cases. The authors noted "in patients having no clinical or radiographic suspicion of malignancy, a persistent abnormal breast thermogram represents the highest known risk factor for the future development of breast cancer"
Jiang LJ, Ng FY et al A Perspective on Medical Infrared Imaging. J Med Technol 2005 Nov-Dec;29(6):257-67 Since the early days of thermography in the 1950s, image processing techniques, sensitivity of thermal sensors and spatial resolution have progressed greatly, holding out fresh promise for infrared (IR) imaging techniques. Applications in civil, industrial and healthcare fields are thus reaching a high level of technical performance. In many diseases there are variations in blood flow, and these in turn affect the skin temperature. IR imaging offers a useful and non-invasive approach to the diagnosis and treatment (as therapeutic aids) of many disorders, in particular in the areas of rheumatology, dermatology, orthopaedics and circulatory abnormalities. This paper reviews many usages (and hence the limitations) of thermography in biomedical fields.
