Never smoked a cigarette? You could still be at higher risk for lung cancer
A rare genetic mutation, specifically the germline EGFR T790M variant, has been linked to a significantly higher risk of lung cancer, even in non-smokers. Studies show this mutation can increase the risk by up to 62 times. This discovery could help explain why some individuals develop lung cancer despite never having smoked.
