Scientists Inch Closer to Developing a Lung Cancer Blood Test
Unlike prostate, colon and breast cancers, the screening for lung cancer hasn’t been very successful. This is largely because screening focuses on just one risk factor, smoking history, yet many people who develop the disease don’t have a history of smoking. Now, scientists have made progress in developing a blood test that could help in flagging individuals who are at a higher risk of developing lung cancer. A new study whose findings appeared in JAMA suggests that it could be possible to scan blood samples and identify signs of possible lung cancer. The test focused on 13 biomarkers and the researchers found that it could identify 85% of lung cancer cases among smokers. Current screening methods using CT…
