abstract：:This commentary celebrates the 40th year of Carcinogenesis, spanning 1980-2020 with a focus on lung cancer. For lung cancer, these 40 years come toward the end of a century of scientific inquiry that began with descriptions of this highly fatal malignancy and that closes with emphasis on molecular processes and genomi...
