Colour cancer is harmful, and timely treatment is the key. The first thing to do before treatment is a variety of tests. For ordinary people, these tests do not have any concept at all, and they do not know what their uses are. Through various examinations, the cause can be judged, and the correct treatment can also be found, which is very helpful for the recovery of the disease. < /p>

　　I believe that everyone has a certain understanding of the disease of colon cancer. With the continuous acceleration of social rhythm, the incidence of this disease is also increasing. Patients often worry about this, living and working. Was severely affected. According to experts, the methods of colon cancer examination mainly include the following five aspects.

　　What are the colon cancer screening methods?

　　1, serum carcinoembryonic antigen (CEA) inspection:

　　pair detection to diagnose colon cancer There is no specificity, and the increase in value is often related to tumor enlargement. The colon tumor can be restored to normal value after complete resection, and it can be increased a few weeks before recurrence. Therefore, it is helpful to estimate the prognosis, monitor the efficacy and relapse. This is a good way to check for colon cancer.

　　2, Type B ultrasound scanning, CT or MRI examination:

　　 can not directly diagnose colon cancer, but the location, size and The relationship between surrounding tissues and the determination of lymphatic and liver metastases have certain value. This type of colon cancer examination is mainly used to understand the extent of tumor infiltration into the intestinal tract and the presence of local lymph nodes or distant organ metastases. It can be pre-operative staging and post-operative review.

　　3. Fecal examination:

　　Through the detection of tumor M2 pyruvate kinase (M2-PK) in feces, it was found that M2-PK in patients with colon cancer The value is 14 times that of normal people. Therefore, the M2-PK detection of fecal tumors provides a promising new method for colon cancer screening, which is also a method of colon cancer detection.

　　4. X-ray examination:

　　includes total gastrointestinal barium meal examination and barium enema examination. This colon cancer examination can observe the full picture of the colon morphology, whether there are multiple polyps and multiple cancer foci, and provide a basis for the surgical treatment of patients with colon tumors. The signs of disease may initially appear stiff intestinal wall, mucosal destruction, followed by constant filling defects, intestinal stenosis, etc. Air-barium double contrast imaging is better.

　　5. Endoscopy:

　　Where there is a change in stool or bloody habits, and there is no abnormality in the rectal finger examination, colon cancer should be checked routinely Fiberoptic colonoscopy. Not only can discover various types of lesions in the colon, but also can take tissue biopsy to confirm the diagnosis, so as to avoid missed diagnosis or misdiagnosis.

　　I believe that the explanation of the above five inspection methods can help the people in need in a timely and effective manner. Many patients in life are afraid of entering the hospital and are nervous about the unfamiliar inspection methods. In fact, if they find a problem You should consult a doctor in time, trust the hospital, and cooperate with a doctor to remove colon cancer quickly and effectively.
