Cancer Detecting Smart Needles

There were over 1.7 million new cancer diagnoses in the US in 2019, with over 600,000 deaths. Most medical experts agree that early detection is key to defeating cancer. Now, a “smart needle” that is being developed in the UK could help root out cancer earlier. 

The device uses a technique called Ramon spectroscopy and a low-powered laser to inspect specific areas. It can spot potentially cancerous cells in seconds.
