While scientists are still working to understand what spurs cancer in so-called 'never-smokers,' a study suggests that 78% to 92% of lung cancers in patients who have never smoked can be treated with precision drugs already approved by the Food and Drug Administration to target specific mutations in a patient's tumor. source https://www.sciencedaily.com/releases/2021/09/210930171022.htm
