Recommendations for general diagnosis of colon cancer

  • Feline fecal analysis should be given once a year - after 50 years for patients with a standard cancer risk, and after 40 years for patients with an increased risk of developing cancer. The method is based on the detection of hemoglobin in a chair, since the tumors are prone to bleeding. Prospecten genetic screening of colon cancer. Cancer cells are allocated with a chair, which means their DNA can be detected. This technique is still being developed. If the analysis of feces on the hidden blood is positive, a colonoscopy is prescribed.
  • Ultrasound of the colon. The non-invasive method of research is also being developed for early detection of colon cancer. The main feature - local thickening of the wall, in which case it is necessary to conduct a colonoscopy.
  • Sigmoidoscopy - an endoscopic examination of the sigmoid colon - should be performed every 3-5 years, with a high risk of cancer - annually. During this procedure, conducted outpatient, is a study of sigmoid and rectum. When a pathology is detected, a colonoscopy is prescribed.
  • Colonoscopy should be performed every 10 years. This is the very best research. Allows you to examine the entire colon and, if necessary, to make a biopsy. For patients at high risk for cancer, colonoscopy should be performed annually.
  • X-ray examination of the colon with double contrast should be performed every 5-10 years. During this procedure, the barrier enema is made, then the air is introduced so that the barium spreads along the inner part of the colon, depicting the inner part of the colon and rectum on the x-ray. The study may not show small polyps or cancerous formations. At detection of pathologies it is necessary to conduct a colonoscopy.
  • CT-colonography (virtual colonoscopy) should be performed every 5 years. She may not show small polyps. At detection of a pathology it is necessary to conduct a colonoscopy.

People with a high risk of developing colon cancer, including patients with polyps, colon cancer in their relatives, inflammatory bowel diseases detected in the previous colonoscopy, colon cancer or precancerous polyps, and hereditary cancer syndrome in a family history, should begin screening at a younger age Age - from 35-40 years.

The exact age of the commencement of surveys and their frequency depend on individual risk factors.
