Lung cancer in a defined geographical area: history and histological types.
Lung cancer was diagnosed in 446 patients during four years in a population living in a defined geographical area in northern Finland. The series comprised 420 men and 26 women, with a male/female ratio of 16.6:1. The diagnosis was confirmed histologically or cytologically in 431 cases (97%). Epider...
