What tests should be done for colon cancer

The treatment of colon cancer is a problem that many people are concerned about. To treat the disease, diagnosis is the first step. In fact, there are many symptoms of colon cancer. If you can pay more attention to your physical changes, you can detect the disease early, and early treatment can control the disease. So what tests should be done for colon cancer?

1. X-ray examination: This type of colon cancer examination includes barium meal examination of the entire digestive tract and barium enema examination. It can observe the overall shape of the colon, whether there are multiple polyps and multiple cancer foci, and provide a basis for surgical treatment of patients with colon cancer. The initial signs of the disease may be intestinal wall stiffness and mucosal destruction, followed by constant filling defects and intestinal stenosis. Double contrast examination of air-barium is more effective.

2. Endoscopic examination: For patients with blood in stool or changes in bowel habits, but no abnormalities found in rectal examination, colon cancer should be routinely examined by fiber colonoscopy. It can not only detect various types of colon lesions, but also take tissue biopsy to confirm the diagnosis, so as to avoid missed diagnosis or misdiagnosis.

3. Serum carcinoembryonic antigen (CEA) test: It has no specificity for detecting and diagnosing colon cancer. Increased values ​​are often related to tumor growth. They can return to normal values ​​after complete resection of the colon tumor. They can increase several weeks before recurrence. Therefore, it is helpful for estimating prognosis, monitoring efficacy and recurrence, and is of great significance for the examination of colon cancer.

4. B-ultrasound scan, CT or MRI examination: None of them can directly diagnose colon cancer, but they are valuable in determining the location, size, relationship with surrounding tissues, lymph node and liver metastasis of the tumor. This type of colon cancer examination is mainly used to understand the degree of tumor infiltration into the intestinal tract and whether there is local lymph node or distant organ metastasis. It can be used for preoperative staging and postoperative review.

If you can prescribe the right medicine, this disease can be cured. Bad habits can cause colon cancer. Patients must treat colon cancer in time. People in life should pay attention to the prevention of colon cancer. In the process of treating the disease, patients should also pay attention to their diet and other issues, so that they can control the disease faster.
