From The BBC:

Portable devices with painless laser beams could soon replace X-rays as a non-invasive way to diagnose disease.

Researchers say that the technique could become widely available in about five years.

The method, called Raman spectroscopy, could help spot the early signs of breast cancer, tooth decay and osteoporosis.

Scientists believe that the technology would make the diagnosis of illnesses faster, cheaper and more accurate.
