Introduction: In Switzerland, lung cancer is a leading cause of cancer death. Because smoking is the major cause of lung cancer, trends in lung cancer incidence are following trends in smoking habits in the population, with a latency time of about 30 years. In Switzerland, there was a peak in men’s lung cancer incidence in the 1980s, followed by a decrease until now. Among women, the incidence has increased since the 1970s and, apparently, has not yet reached a peak. Because cancers are feared diseases, an adequate communication about the individual risk of developing cancer is important. Mortality and
incidence are traditionally used to assess cancer burden. However, these metrics are difficult to interpret at the individual level. Providing the lifetime and 10-year risk of cancer could improve risk communication for patients and health professionals. Our aim was to estimate trends in the lifetime and 10-year risk of lung cancer, in men and women, between 1995 and 2013.
