Semiconductor devices could one day convert sound into light at terahertz frequencies, a radiation range that can detect skin cancers before they are visible on the surface. Such light could also provide a privacy-protecting alternative to naked body scanners in airports

Like the ultra sound and maybe a little like a MRI, you can find the residence frequency of normal cells, and the frequency of cancer cells.
Using a little discrimination the cancer cells easily couple be located and isolated. The Cool factor here is the conversion method between light and sound, not so much the detection, a ultrasound can see tumors.
We used Ultrasound(legal in Europe) to "Burn" out cancer cells in the prostate, some of these higher frequency sounds have great effects that are just being made operational. Wait till we know more about magnets because MRI uses a by-product of the magnetic field to make the image.
