Scientists in the UK have developed a “smart needle” designed to accelerate cancer detection and diagnosis in potential lymphoma and other cancer patients. This device uses Raman spectroscopy to shine a low-power laser into the body which can measure molecular changes and identify cancerous tissue within seconds. This new technique has the potential to reduce the need for diagnostic surgery and help speed up the diagnosis process, which can often be time consuming and expensive.

The experimental technique is still in its initial development phase, having started clinical trials last year.
