Prospector, Thanks for the links from George. The link to post #45 is the key one. It links to an article from a company called Inframetrics (potential competitor???) that, in part, gives some past history on a multicenter study sponsored by the National Cancer Institute comparing mammography, thermography, and palpation . This study is interpreted as promising for thermography, and may be the basis for Dr. Cockburn's claims that I have previously questioned the basis for. Several points are crucial to note: 1. The statement "One experiment...demonstrated...a number of instances where early detection was confirmed by mammography findings months and years later" is perhaps the basis for concluding that thermography is superior to mammography - and perhaps it is - but you can't prove it by this, so far. First, it does not say these lesions were missed by mammography initially, and then found months and years later; it could very well be that only thermography was performed initially, and mammography at a later time. Had mammography been done simultaneously, it may have found the lesions too. Second, the article clearly states that mammographic techniques have improved considerably since that time, so it is not clear until results of the current study are out ( and perhaps not even then, because this study is not designed to see if thermography can pick up lesions missed by mammography) whether thermography can indeed pick up lesions missed by mammography, as claimed by Dr. Cockburn. Now, before anyone jumps me, I'm not saying it can't, I'm just saying it isn't proven yet, as far as I know, so claims to that effect should be taken with a grain of salt! 2. The article cited clearly states "all three modalities presented disappointing results". Again, I recognize the technology has improved since then. All I'm saying is that the older studies are not as convincing to me as they apparently are to some others. Bob
