Prognosis
As more than two thirds of lung cancers are diagnosed at a late stage, lung cancer generally has a poor prognosis. Only 15% of patients with lung cancer survive more than 5 years after diagnosis, with 13% of men and 17% of women.
Better diagnosis and treatment of lung cancer, combined with drop in tobacco consumption which started in the mid-60s for men mean a declining incidence for men which began in the 1980s. Incidence and mortality for women are beginning to level off as tobacco consumption started declining in women in the 1980s.
