According to research findings, not all types of intestinal cancers can be diagnosed with colonoscopy.
Colonoscopy is a diagnostic test that allows you to detect neoplasms using a small chamber that is used to examine the colon and rectum. Currently, this diagnostic method remains the best to detect early signs of oncological bowel disease. However, a new study showed that colonoscopy misses up to 7% of cases of colorectal cancer.
Colonoscopy helps to prevent the development of colon cancer by removing precancerous polyps. However, scientists from the University of Manitoba found that most cases of colon cancer, diagnosed within three years after a colonoscopy, began with tumorous lesions that had been missed with initial diagnosis. The study suggests that early stages of the disease can not be noticed when localizing a tumor in the right half of the colon, during colonoscopy by a general practitioner and during colonoscopy in women. However, this procedure is still a method of choice for the screening of patients with certain symptoms, such as elderly people with rectal bleeding.
How to protect the health of the intestines
- Observe the terms of colonoscopy. For many people, this means a regular survey from the age of 50. You should check with your doctor if you have any risk factors that may require such an examination.
- Be alert about the symptoms associated with the intestine: the presence of blood in the stool, various changes in the stool (violations of the regularity of the chair, etc.) and abdominal pain.
- Do not forget about anesthesia during the procedure. Studies have found that pictures of patients who were pre-anxious were much better.
- The procedure must be properly prepared. Very often the intestine is poorly prepared in its right half, just where there is a higher risk of not spotting the tumor.
