|Breast thermography measures the infrared radiation (heat) which is constantly radiating (emitting) away from the surface of the human skin. Skin as an organ breathes, exchanges gases with the environment, cools us as well as keeps us warm by letting heat out or keeping it in by controlling the amount of circulation, or blood flow, in the skin. This automatic regulation is done without conscious thought and is controlled by the autonomic nervous system via the sympathetics. The whole process is called thermoregulation.
The procedure is based on the principle that chemical and blood vessel activity in both pre-cancerous tissue and the area surrounding a developing breast cancer is almost always higher than in the normal breast. Since pre-cancerous and cancerous masses are highly metabolic tissues, they need an abundant supply of nutrients to maintain their growth. In order to do this they increase circulation to their cells by sending out chemicals to keep existing blood vessels open, recruit dormant vessels, and create new ones (neo-angiogenesis). This process results in an increase in regional surface temperatures of the breast.
Abnormal thermological patterns of the breast clearly demonstrate abnormal areas of heat. This gives the clinician an alert that something might be wrong with physiology of the breast. It could be an infection, inflammatory process, trauma or cancer.
The procedure is both comfortable and safe using no radiation or compression. By carefully examining changes in the temperature and blood vessels of the breasts, signs of possible cancer or pre-cancerous cell growth may be detected up to 10 years prior to being discovered using any other procedure. This provides for the earliest possible detection of cancer. Because of breast thermography’s extreme sensitivity, these temperature variations and vascular changes may be among the earliest signs of breast cancer and/or a pre-cancerous state of the breast.
Studies show that:
Breast thermography is not a stand-alone tool in the screening and diagnosis of breast cancer. It is adjunctive. We can not ignore the tremendous role of breast thermography as an early risk indicator or as a monitor of treatment. When a thermogram is positive, a closer look at the patient’s diet, exposure to environmental pollution, toxins and lifestyle is in order. Clinical blood work in addition to ultrasound and mammography is essential. When mammography and blood work are negative or equivocal, thermographic monitoring on a quarterly to semi-annual basis should be performed in those patients with suspicious thermograms.
Changes in tumor angiogenesis can be evaluated and other procedures can be ordered to aid in the earliest possible diagnosis. Breast thermography is non-ionizing and safe and there is no reason to simply “wait and see” any longer. It is at this stage that a major decision must be made. We can no longer be passive but must become proactive with our health. The “wait and see’ just because a mammogram is negative or equivocal is no longer acceptable. With a more universal non-political approach, thermal imaging can become a valuable early detection tool that is indispensable in patient’s health care. Since it has been determined that 1 in 8 women will get breast cancer, we must use every means possible to detect cancers when there is the greatest chance for survival. Proper use of breast self-exams, physician exams, breast thermography, and mammography together provide the earliest detection system available to date. If treated in the earliest stages, cure rates greater than 95% are possible..
