[Gender-specific difference in lung cancer]

More and more differences in lung cancer are being detected between men and women. Lung cancer, at the beginning of the last century a rare disease in women, has a growing incidence in women, in particular in young females. Lung cancer is a leading cause of cancer death in women in developed countries with different histological types and adenocarcinomas are more frequent in women than in men. Cigarette smoking is the most prevalent cause of lung cancer in women, in addition susceptibility to carcinogens may differ between the sexes. As more non-smoking women than men develop lung cancer, it is likely that they are exposed to excessive environmental carcinogens such as second-hand-smoking, in-house-radon or cooking fumes. Furthermore, genetic and hormonal influences play a role in lung cancer etiology for women. Taken together, women have a better overall survival than men with lung cancer. Differences in molecular susceptibility patterns are observed between men and women, and show that molecular targets such as EGFR or ALK more frequent in women.
