Ok, I dont know a whole lot about thermography/ thermology, but it's less harmful than X-ray, and is good for many more things. So why isnt it being used readily in the medical world???
Dont get me wrong, X-rays are the best for detecting broken bones, or anything related to the skeletal structure, but thermology deals with circulation, and heat differentials. Its the best/ painless/ safest way to dectect cancer! (especially if your a woman, who would like her breasts not to be flattened by a mammogram.)
