Genetic mutation raises lung cancer risk twentyfold
Researchers have reported that a rare genetic mutation in the Epidermal Growth Factor Receptor (EGFR) gene significantly increases the risk of lung cancer, especially among non-smokers, with the risk rising up to 60 times compared to those without the mutation. A study involving data from over 3.3 million people showed that carriers of the "EGFR T790M" mutation are more susceptible to developing the disease, which may open the door for genetic testing in early detection efforts. The findings highlight the importance of screening for inherited genetic risk factors alongside smoking history to identify individuals most vulnerable to the disease.
