Mammograms Beat Thermography for Breast Cancer Detection, Bryn Mawr Hospital Study
Published: May 08, 2012
Thermography -- a breast cancer detection method touted by some as a substitute for mammography -- is an unreliable cancer screen, according to new research. In a study of about 180 women, thermography missed about 50 percent of cancers and delivered too many false positives, said Dr. C.M. Guilfoyle, a researcher at Bryn Mawr Hospital in Pennsylvania. The radiation-free screening method uses computer software to measure and compare thermal abnormalities in the breasts and create a breast "map" to look for signs of developing breast cancer. The thinking is that increased temperature is found in areas with increased blood flow, and that may indicate a tumor.
