Colon cancer is one of the more common cancers in the human body.

Before treating colon cancer, people must conduct detailed examinations, so that they can better get rid of the torture of the disease. The following experts will answer questions about the common methods of colon cancer examination.

1. Fecal occult blood test Usually, there may be no signs of the occurrence and development of colorectal cancer in the early stages. Cancer cells can grow on the intestinal wall for decades and then metastasize to other parts. Before there are any symptoms, the proliferating tissue can exude a small amount of blood, which enters the stool and is excreted. The fecal occult blood test is to detect the blood components in the stool. If multiple and continuous positive reactions indicate gastrointestinal bleeding, further examinations should be done to alert the occurrence of intestinal tumors.
This test is currently the most widely used and evaluated test method in colorectal cancer screening. It is simple, quick and painless.
2. Serum carcinoembryonic antigen test Although serum carcinoembryonic antigen test does not have specific diagnostic value, it is of great value in estimating the prognosis of colorectal cancer, detecting efficacy and recurrence.
3. Colonoscopy: For patients with blood in stool or changes in bowel habits who have no abnormalities found in rectal examination, sigmoidoscopy or fiber colonoscopy should be performed. Currently, fiber colonoscopy is the most effective, safest and most reliable method for diagnosing intestinal lesions. Most early-stage colorectal cancer patients can be detected and diagnosed by endoscopic examination.
What are the other common methods of colorectal cancer examination? Experts point out that when people deal with colon cancer, in addition to actively dealing with the torture of the disease, they must also pay attention to taking good care of the disease during the treatment of the disease.
