DNA measuring blood test could detect lung cancer early

February 13, 2019

The circulating DNA is released by cancer cells into the blood during their growth and multiplication. Measuring these DNA levels is also expected to enable the prediction of tumours in the lungs even before they turn cancerous.

During the study, the team used mice with KRAS mutation as models for the pre-cancerous lung cancer stages. Standard computed tomography (CT) scans were used to track the development of small pre-cancerous lung tumours.
