New test could give smokers early warning of lung cancer

Scientists have discovered that the way light reacts with human cells may indicate the likelihood of a person having lung cancer.

Patients with lung tumours were found to have subtle abnormalities in the cells of their mouth, lungs and nose.

Using swabs from patients’ cheeks, researchers from University College London found that cells of lung cancer patients reflected and refracted light slightly differently to those who did not have the disease.
