The image to the left show a very fast growing tumor. The thermal images show the heat associated with the tumor in July 2012. In only a few months the tumor broke the skins surface and by January showed this thermal impression. Cancer cells can divide fast. Do not rely on any one technology for early detection. Studies have shown thermography can find tumors up to 10 years before a mammogram in 70% of the cases according to a University of Wisconsin study; as well as a concurrent Russian study that showed approximately the same results.
