Cancer incidence and mortality rates have been increasing in Turkey as most of the developing countries. Besides socioeconomic factors, one of the most prominent attributes of developing countries is the dissimilarity of their age-dependent demographic structure. In Turkey, cancer incidence rates rise due to individual and environmental risk factors as well as due to the improvement in the registry system and to increase in access to health services. According to the data retrieved from the Ministry of Health Department of Cancer Control database cancer incidence rates increased between 2002 and 2005. Incidence rates rose from 133.78 per 100 thousand in 2002 to 173.85 per 100 thousand in 2005. Between 2002 and 2005 the average growth rate of increase for men comes about 9.7%, which is higher than 8.6% for women leading to the widening of incidence gap between man and women. First five frequent cancer types in Turkey are lung (30.13), prostate (24.33), skin (18.91), breast (17.96), stomach (9.92) cancer with an incidence of per 100 thousand. Cancer incidence growth rates for men exceed the cancer incidence growth rate for women. This gap is resulting mainly from lung cancer incidence which is much higher for men. Further extension of the nationwide cancer screening and prevention programs will result in improvement of cancer control.
