University Of Pittsburgh Scientists Find Biological Clue To Why Ex-Smokers Develop Lung Cancer Many Years After Quitting
Researchers at the University of Pittsburgh Cancer Institute have found a biological switch that drives the growth of lung cells in ex-smokers, leading to an increased risk of lung cancer. The 'switch' is triggered by gastrin-releasing peptide (GRP) receptors, which capture circulating hormones and spur lung cell division.
