Blood test could spot lung cancer early
A blood test has offered hope of finding cancers before symptoms develop. The test that analyses free-floating DNA in blood may be able to detect early-stage lung cancer.
The findings are from one of the first studies to explore whether sequencing blood-borne DNA is a feasible approach to early cancer detection. Early diagnosis is essential to improve survival rates for lung cancer. A blood test that could be done through a simple blood draw at the doctor’s office could potentially have a major impact on survival.
Tests that analyse cell-free DNA in blood, known as ‘liquid biopsies’, are already used to help choose targeted therapies for people already diagnosed with lung cancer.
