Colonoscopy: These Facts You Did Not Know Yet!
Since the risk increases with age, all those insured under the age of 50 are entitled to such an examination. If there are no special risk factors (eg familial stress, diabetes mellitus type 2), the colonoscopy can be repeated after ten years – otherwise more often. The aim of colonoscopy is to detect polyps or suspicious changes in the intestinal mucosa and to remove them immediately. Colonoscopy is one of the most reliable preventive medical examinations when physicians – as is customary in Germany – perform them according to high hygiene standards and in certified practices. Serious side effects are very rare.
So far you have not known these facts: Colon cancer is one of the best researched cancers!
How Can Colon Cancer Develop?
90 percent of all intestinal tumors develop from polyps of the intestinal mucosa. In about 30 to 40 out of 100 people over the age of 60, one or more polyps are found in the reflection. They usually cause no symptoms. Men are affected more frequently than women. The polyps usually develop from the intestinal mucosa (adenomas) and grow very slowly, about one millimeter per year. The risk of developing cancer after several years increases with the number of polyps and age. If more than three polyps are discovered or a particularly large, colonoscopy is performed at shorter intervals. Genetic factors can cause many young people to develop many polyps (familial adenomatous polyposis).
What Are The Causes?
In Europe, the USA and Australia, the intestinal cancer tumor occurs much more frequently than in Asia and Africa. Lifestyle and nutrition play a central role. Studies show that overweightPeople, but also diabetics more often have intestinal polyps. Too little exercise, low-fiber and fatty foods, as well as tobacco and alcohol increase the risk of intestinal polyps. In some families, mucosal proliferation in the intestine is more common: in every third person, relatives also have tumors or polyps. Of these, 20-25 percent of the reasons are unknown, that is, “familial accumulation”. In five to eight percent of these patients, specific genetic changes can be detected. These include HNPCC (hereditary non-polyposis colorectal cancer) or familial adenomatous polyposis (FAP). With these gene mutations you should start with the precaution even at an adolescent age.
And That’s How The Colonoscopy Works Out
Preparation: About 24 hours before the examination you should not eat any solid food. Depending on the time of the appointment, you can drink a laxative in the evening or in the early morning. Finally, one must excrete only clear liquid.
Anesthesia: Patients often receive anesthesia before colonoscopy. The colonoscopy takes about 20 minutes. Depending on the medication administered, the caregivers may not drive for several hours, must be picked up by a trusted person and possibly cared for for a short time.
Examination: One and a half meters long is the colonoscope, a flexible, thin tube with a light source and a camera at the end. On a screen, the doctor can thus look at the entire colon and remove loops or forceps on the head of the colonoscope suspicious tissue sites. Subsequently, they are examined in the laboratory for cancer.
