Why is a thermogram so effective?

 Prior to a tumor being formed, cells in the breast begin to create a cancer-friendly environment. Part of this process involves angiogenesis, the development of new blood vessels. These blood vessels provide a blood supply to the area for the cancer to grow. The process of angiogenesis creates heat patterns. Thermography, being sensitive to fluctuations in temperature, can detect these changes in the breast far earlier than other screening methods. Numerous studies have shown that infrared can detect the signs of developing cancer years before modalities such as mammography; by up to 10 years, and that it is a good indicator of risk for breast cancer.
