Portable devices that use laser beams may soon replace X-rays in the diagnosis of breast cancer, tooth decay and bone diseases.

These devices work on the principle of Raman spectroscopy, where a laser is focused on tissue to determine chemical composition, according to BBC.

The chemical composition can be analysed to diagnose diseases in a few minutes.

Devices using Raman spectroscopy would be non-invasive, painless, cheap, accurate, and could help in earlier diagnosis and treatment of diseases.

They could be available within five years, according to scientists.
