Annie Chen 是在 2017 年第一次注意到异常的呼吸急促，家庭医生告诉她不要担心，她的父亲有重烟瘾，71 岁时因肺癌去世，但她从未吸过烟。两年后医生给她做了 X 光检查，显示肺癌晚期。Chen 女士的病例代表了研究和治疗肺癌的医生所面临的一个日益困惑的现实。因吸烟率下降，过去几十年肺癌的发病率和死亡率也在下降，但非吸烟的肺癌患者的比例则出现了增长。研究人员估计，全球约有 10%-25% 的肺癌患者从未吸烟，在部分亚裔和亚裔美国女性人群中，比例可能高达 50% 或以上。对全世界 871 名非吸烟肺癌患者的研究发现，对于生活在空气污染严重地区的人群，某些 DNA 突变更为常见。污染不仅会直接损害 DNA，还会加速细胞分裂。非吸烟肺癌病人的癌症生物学特征与吸烟者不同，可能需要不同的预防和检测策略。非吸烟肺癌患者更有可能携带特定的致癌突变，而吸烟者则会随着时间推移积累更多突变。
