Frequently Asked Questions
Is breast thermography safe?
Yes. Thermography is FDA approved in the US and has been used in Europe and in many countries around the world for over 30 years. Thermography is a non-invasive test, which means nothing is sent into your body. Images that are created by this technology are simply measurements of the heat that naturally radiates from your body. There is no contact of any kind, nor is there any pain or radiation.
Can breast thermography diagnose breast cancer?
Thermography cannot, and does not, diagnose breast cancer. This is also true for anatomical tests, such as mammograms, ultrasounds, and magnetic resonance imaging. Such tests provide information on the different aspects of the disease process and identify the need for further investigations. A biopsy of the breast and accompanying histological evaluation is the only definitive diagnostic test for breast cancer. Many of our patients come in after an equivocal “lets watch this area” mammography, and correlate the area to be monitored with a thermographic image of the same area. If the thermography findings appear high risk with the same area of interest, the patient will have more information with which to make an informed decision.
Does OHIP or Medicare cover breast thermography?
No. However, many private insurance companies cover the cost of this examination.
Have any studies been done regarding the accuracy of thermography?
Absolutely! Hundreds of studies have been written up in peer-reviewed medical journals over the years. For a list of these studies, please go to our Studies Section http://www.thermographyclinic.com/study-index
Do I need a referral from my family doctor?
No. A referral is not necessary.
How long does a thermography scan take?
This procedure, including time to acclimate in the room, takes 30 minutes.
How often would I need to repeat this procedure?
This depends on your initial findings. With low risk findings, and depending on your age and general level of health, we will recommend annual or bi-annual screening. If your findings fall into the higher risk category, you will be asked to repeat this examination in 6 or 9 months to compare to the baseline. Because the thermogram of a healthy woman remains remarkably constant, serial thermograms can assess tissue changes over time. A healthy initial thermogram can, therefore, serve as a baseline to compare future thermograms against.
We will ask you to escalate to structural tests to make sure that nothing is being missed at that time. In the event that your other tests come back with negative results we will continue to monitor you with greater frequency (please see the answer above) to make sure that there are no changes compared to your baseline images. We will also advise you to look at some of the risk factors that may be elevating your rating. These may include hormonal issues, diet, nutritional disturbances, endocrine disorders, and lifestyle modifications, just to name a few.
Does thermography replace mammography?
No. Thermography is not a stand-alone diagnostic test when it comes to breast cancer. Thermography differs from mammography in that it provides information on the biological activity of the breast versus the gross internal anatomy. Infrared imaging is a functional test, whereas mammography is a structural test. We recommend that, when necessary, thermography be used in conjunction with other structural examinations (mammography, ultrasound, or MRI) for the most comprehensive screening and the earliest possible detection of malignancy.
I have breast implants, is it safe to use thermography?
Yes. Breast thermography is painless and safe, using no radiation or compression. It can be used effectively and safely for all women, including pregnant or nursing women, women with dense breast tissue, women with fibrocystic condition, and women with breast implants.
Why do we have you plunge your hands in to chilled water? (Cold challenge test)
During your thermography test, you will be asked to plunge your hands into 10C water for 60 seconds. Your thermography technician will then repeat the process of imaging, providing before (baseline) and after (functional) images. Under normal, healthy conditions, your blood vessels will constrict, which a normal physiological response. However, high-risk areas will not respond to this challenge at the same rate as the healthy surrounding tissue. The cold challenge test provides us with additional information that aids in our comprehensive analysis of your images. Thermography is a test of physiology that measures physiological response (dynamic testing vs. static testing), thus a cold challenge test provides us with additional physiological assessment. Breast thermography clinics that do not perform a cold challenge test are making a grave mistake and doing a disservice to their clients by not following international standards and, in effect, performing only half the test.
Please note, if you have Raynaud’s or any other condition that would prevent you from taking the cold challenge test during your thermography session, please inform your thermography technician, who will provide you with an alternative protocol that will not affect your condition.
How come thermography is not embraced by mainstream medicine?
As a stand-alone test, thermography has been criticized for its high rate of false negative and false positive results. Historically, infrared cameras lacked the sensitivity to detect subtle temperature changes necessary to identify and monitor disease. Since the 1990’s, major advancements in infrared technology, coupled with sophisticated computerized software programs, have resulted in a significant increase in the accuracy of thermal images. For example, a 4-year clinical trial by Parisky and colleagues demonstrated 97% sensitivity in the detection of breast cancer with the use of dynamic, computerized, thermal imaging. In another recent trial, modern digital thermography was also able to detect 97% of biopsy-confirmed breast malignancies.
One of the key benefits of thermography is its effectiveness in women with dense breasts, making it suitable for:
