[Diaphanography of the breast: myth or reality?]

The old method of diaphanoscopy or transillumination is generally considered by most physicians to be as non-invasive as it is needless. However, since the beginning of the eighties, thanks to the video camera, the computer, the use of red and infrared lights, new modes of application of this method have been possible; i.e. diaphanography, light scanning, diaphanoscopy, in vivo spectrometry. Two fields of indications for diaphanography are now evaluated: 1) In breast cancer detection and diagnosis, interesting results are claimed. The discussion about the comparison of these results with those of mammography may be long and hard. 2) In the evaluation of the richness of the structures of the breast, diaphanography offers unique possibilities. It has a special ability for the detection of local or general hyperplasia which is positively correlated with the risk of cancer. It may be too early to appreciate with certainty the value of these new modes of application of diaphanography, but its theoretical background shows that it is able to offer original information. Therefore, considering the difficulties and the importance of the diagnosis of breast diseases and the limits of the methods today in use, we should feel compelled to develop this examination procedure.
