title: [Epidemiology of colorectal cancer].
abstract: Colorectal tumors are among the most frequently encountered forms of cancer worldwide. With approximately 57,000 new cases every year, they represent the most frequent type of cancer in Germany, ranking before breast cancer (approximately 46,000) and lung cancer (approximately 37,000). Although global incidence is on the rise, in Germany it is only increasing among men, but not among women. The mortality rate (approximately 26,500 deaths annually) in Germany has declined among men for about the past 10 years and among women for about the past 20 years. The most important risk factors are familial history of colorectal and other tumors as well as lifestyle factors such as nutrition, obesity, inactivity,and smoking.Lifestyle-related risks offer a broad area for implementing primary preventive measures,which have not yet been adequately exhausted. Several proven (fecal occult blood test) and probably effective (endoscopic) methods are available for secondary prevention. Consistent encouragement of these possibilities for prevention could reduce incidence and mortality substantially and render colorectal tumors less frequent.
