[Life style modification in lung cancer prevention].

According to the recent data tobacco use increases the mortality rates due to cancers by about 30-40%. Active smoking is responsible for approximately 80% incidents of lung cancer while passive smoking attributes to 20-60% increase in lung cancer morbidity. However, in Poland as well as in other European countries a certain decline in the number of new incidents and death rates due to lung cancer has been observed. These positive changes seem to reflect a decrease in prevalence of tobacco use in the industrialized world. It is also well documented that lung cancer can be avoidable by the means of appropriate diet and physical activity level.
