A: According to the FDA, “Thermography is a noninvasive tool that uses an infrared camera to produce images (thermograms) that show the patterns of heat and blood flow on or near the surface of the body. Thermography devices, also known as digital infrared imaging devices, have been cleared for marketing by the FDA only for use with another screening or diagnostic test like mammography, not for use as a standalone diagnostic tool.”
With breast thermography, an infrared image captures temperature data from your breast. The thought behind this method is that breast cancers have increased metabolic activity and angiogenesis. So areas with cancer will reflect higher temperatures than normal parts of the breast.
Mammography is a specially designed X-ray technique that provides high-definition views of the breast tissue in order to screen for breast cancer. Screening mammography has been well validated by numerous randomized controlled clinical trials and is the only method (in comparison to breast ultrasounds, breast MRIs, etc.) shown to decrease breast cancer-related deaths.
The FDA has also stated that “thermography is not an effective alternative to mammography and should not be used in place of mammography for breast cancer screening or diagnosis.” In addition, “there is no valid scientific data to demonstrate that thermography devices, when used on their own or with another diagnostic test, are an effective screening tool for the early detection of breast cancer.”
Also, The Society of Breast Imaging has stated that it does not currently support the use of thermography as a screening tool in the detection of breast cancer or as an adjunctive diagnostic tool.
Mammography is very well tolerated by the majority of patients. There are a few circumstances where someone might not be able to undergo screening mammography. Some examples of this are if a patient is very sick, has limited mobility or is pregnant. In these special cases, other testing alternatives may be appropriate and would be determined by the patient’s doctors.
Breast imaging specialists in general support the argument that thermography should never be a replacement for mammography, regardless of the patient’s underlying medical condition. Additional studies in the future are needed to determine whether there is any evidence that thermography in combination with mammography would be useful for breast cancer screening.
