Colorectal Cancer Early Detection

Colorectal Cancer – Early Detection, It is assumed that in early diagnosis 90 percent of all colorectal cancer patients can be cured. Therefore early detection plays an important role in colorectal cancer. For this reason, the legislator has created the possibility of early detection and preventive examinations from the age of fifty. The following procedures are recommended in the “Health Guideline Early Detection of Colorectal Cancer” of the Oncology Guidelines Program.

Recommended tests for the early detection of colorectal cancer:

Palpation

During the examination, the doctor carefully feels the rectum. The end-canal carcinomas close to the anus can be detected early and partly in precursors by means of this tracer examination.

Colorectal Cancer – Early Detection Stool Test

The stool test can detect the smallest amounts of blood in the stool and thus give initial indications for a bowel tumor or polyps . The chair test takes place at home. Using a spatula, carry a test sample on test strips for three consecutive days and send it to your doctor. If the test is negative, that is, there is no blood present, the examination is completed. If the test is performed annually, the benefit increases, and about three out of every 1,000 people have been saved from colorectal cancer.

Colorectal Cancer – Early Detection Colonoscopy

In colonoscopy, a distinction is made between “small” colonoscopy (sigmoidoscopy) and “large” colonoscopy (colonoscopy) , which is currently the most reliable method for early detection of colorectal cancer, colonoscopy can also include the precursors of colorectal cancer, And in some cases in the same session, colonoscopy is not only an early detection but can also prevent the development of colorectal cancer in precursors, and many experts therefore strongly recommend using the possibility of colonoscopy do.

In the case of sigmoidoscopy , the examiner looks at the last 60 centimeters of the colon. Here about two thirds of all intestinal tumors are found. During the examination, the patient lies sideways on a couch, while the doctor introduces a flexible, approximately finger-thick tube into the intestine. At the front end of the tube, the so-called endoscope , there is a light source and a camera. While the examiner slowly withdraws the tube slowly, he can view the large intestine mucosa in a multiple magnification on one screen. If he sees suspicious tissue, he snaps samples from them with a small forceps, which is also pushed through the tube, and pulls them back through the tube. Many growths, for example, polyps, can be removed with the forceps or a sling during colonoscopy. The collected samples, so-called biopsies , and the removed growths later examined a pathologist under the microscope. Thus, it is determined whether the examined tissue contains good or malignant changes.

The examination itself usually takes about five minutes. If you are afraid of the examination, you can get a sedative.

 If the examination results in a conspicuous result, the experts recommend a large colonoscopy for further clarification.

In colonoscopy the whole colon is viewed, not just the last 60 centimeters. The doctor explains a few days before how the examination will be prepared and what you should follow. Colonoscopy may only be performed by physicians who have acquired a special qualification.

In colonoscopy the physician introduces a finger-thick tube into the rectum and pushes it through the entire colon to the small intestine. In the intestine some air is blown in, then the examiner pulls back the tube very slowly. As in the case of sigmoidoscopy, he can view the colorectal mucosa on a screen in an enlarged manner, take samples at suspicious locations and remove polyps. The examination usually takes about half an hour.

In this study, too, the patient can first receive a sleeping remedy that puts him in a kind of sleep. Even on the day of colonoscopy you can eat everything again. If the patient has received a sleeping agent, do not drive this day.

Before colonoscopy the colon must be completely emptied. As only one empty bowel can be reliably assessed, a good preparation is very important: two days before the colonoscopy, one should therefore dispense with hard-to-digest foods. From the evening before the examination the patient should not eat anything and take a laxative. Or he drinks a rinse solution on the morning of the test.

Not recommended procedures for the early detection of colorectal cancer:

  •  ·       M2-PK test
  •          DNA stool test
  •  Capsule Colonoscopy
  • ·         CT and MR colonography
