Blood test could provide early lung cancer diagnosis say scientists
A simple blood test currently in early-stage testing could provide a fast and reliable means of diagnosing the most common form of lung cancer, say scientists.
The test was developed by looking for specific antibodies - proteins made by the immune system in response to infection and other disease - that were present in the blood of patients with non-small cell lung cancer.
The results now need to be confirmed in wider studies.
"These data suggest antibody profiling could be a powerful tool for early detection when incorporated into a comprehensive screening strategy," claimed the report.
Non-small cell lung cancer is the most aggressive form of the disease around the globe, claiming around 11 million lives annually. Only about half of patients survive more than a year after diagnosis.
As the disease is often picked up late on, when treatment is difficult, an effective diagnostic or screening test could save many lives.
The study was conducted by the University of Kentucky and published in the Journal of Thoracic Oncology.
