[Lung cancer in Finland]

Lung cancer incidence in Finland ranked first in the late fifties. In the seventies, 2,000 new cases of lung cancer in males were registered annually, i.e. more more than a third of all newly-registered cases of cancer. At present lung cancer ranks tenth in females. About 300 new cases (nearly 5% of all primary malignancies) are reported every year. Every effort must be made to comprehend the etiology of lung cancer and to develop methods of its prevention.
