Increased inflammation may be a warning of elevated lung cancer risk. A recent study analyzed blood samples taken from over 1,000 patients getting screened for lung cancer. Half of the patients went on to develop lung cancer in the following years. Eleven chemical markers of inflammation in the patients’ blood were associated with an increased risk of developing lung cancer. The researchers developed an inflammation score based on the levels of four of these inflammation markers. Patients with the highest inflammation score were 2.8 times more likely to develop lung cancer than those with the lowest score (3.4 times more likely if the patients were current smokers). This inflammation score may therefore serve to identify high-risk patients in the future.
