Prevention of colon cancer
The lifestyle makes a lot
The development of adenomas and thus also colorectal cancer can be prevented by a healthy lifestyle. The diet, a healthy body weight and physical activities have a particularly high proportion. It is assumed that if a healthy lifestyle is maintained, 50 to 70 percent of all colorectal cancer can be prevented.
Numerous scientific studies have shown a link between the diet and the risk of colorectal cancer in the past. A high proportion of dietary fiber by fruits and vegetables, fish and minerals such as calcium in the daily diet can protect against colorectal cancer. Flavonoids of green tea and chamomile also prevent cancer. Regular consumption of red meat (eg pork, beef, game) and processed meat (eg sausage, salami) and regular high alcohol consumption are associated with an increased risk of colorectal cancer.
overweight and obesity (particularly obesity), especially when associated with a lot of abdominal fat, increase the risk of colorectal cancer. The causes for this effect have not yet been clarified. In addition, there are changes in fat and sugar metabolism due to the increased body fat, but also the influence of various hormones such as insulin and steroid hormones, as well as factors that influence the growth of tissues, such as the insulin growth factor 1 The immune responses. In any case, it is recommended to maintain a healthy body weight with the lowest possible proportion of abdominal fat.
A lot of physical activity prevents the development of adenomas and colorectal cancer and also has a beneficial effect on the progression and the prognosis. This relationship is clearly demonstrated for malignant tumors of the colon: the risk of colorectal cancer is reduced by more than seven hours per week by 40%. The effects of sport on the development of the rectal carcinoma are still unclear. Individual studies have observed effects similar to those of colorectal carcinoma, but in other studies there were no benefits from physical activity.
Why sports can reduce the risk of colorectal cancer is still under discussion among experts. It is assumed that potential cancer cells are dying by the intense movement. Moreover, tumor suppressor genes are increasingly being formed, which suppress the growth of cancer cells. Particularly favorable are obviously sports such as swimming, cycling, dancing or jogging.
Regular preventive examinations
Another preventive step in the prevention of colorectal cancer is the screening. (LINK to the section “Early Detection”) They aim to detect not only colorectal cancer in the early stage, but already its precursors, the so-called adenomas. These can be removed immediately during the colonoscopy so that no cancer can develop from it. Experts believe that colorectal carcinoma can be prevented in 75 to 90 percent of all cases by regular screening. For persons who have an increased risk of colorectal cancer due to a family history, hereditary changes or certain diseases, special recommendations apply with regard to the screening examinations
