NIH study illuminates origins of lung cancer in never smokers

摘要

2021 SEP 21 (NewsRx) - By a News Reporter-Staff News Editor at Disease Prevention Daily - A genomic analysis of lung cancer in people with no history of smoking has found that a majority of these tumors arise from the accumulation of mutations caused by natural processes in the body. This study was conducted by an international team led by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health (NIH), and describes for the first time three molecular subtypes of lung cancer in people who have never smoked. These insights will help unlock the mystery of how lung cancer arises in people who have no history of smoking and may guide the development of more precise clinical treatments. The findings were published September 6, 2021, in Nature Genetics.
