New research has identified a potential early warning system for lung cancer.
Researchers from the University of Nottingham claim that changes in the blood which signal the presence of lung cancer can be detected years in advance of any apparent outward symptoms.
In collaboration with researchers from Johannes Gutenberg University in Germany, the team from Nottingham tested samples from 50 healthy participants and 104 lung cancer patients.
They noted the presence of seven autoanitibodies associated with 'solid tumors' in approximately 80 per cent of the lung cancer patients.
The autoantibodies were also found in eight out of nine patients whose cancer had not progressed past the lymph nodes and therefore had an 80 per cent chance of being cured.
According to the authors of the study, a blood test is the ideal way to test for lung cancer as they are cheap, have no side effects and can be optimised to identify a a range of autoantibodies.
Lung cancer is the second most common caner in the UK, according to Cancer Research
