Apparatus for imaging of the inner structure of the breast, the apparatus comprising: a source of light illuminating the breast when the source of light is situated at a first position of the breast; and a detector which when situated at a second position relative to the breast, detects light from said source passing through a portion of the breast from the source; wherein the source of light comprises either: a non-laser radiant source and at least one optical filter situated between source and the detector that limits the light reaching the detector from the source to a visible spectral band limited to wavelengths in the range from 490 to 510 nanometers or 520 to 580 nanometers; or a source of laser light operating at an output at between 490 and 510 nanometers or between 520 and 580 nanometers or is a tunable laser light source operating at a wavelength between 490 and 510 nanometers or between 520 and 580 nanometers.
