Methods for diagnosing colon cancer

The incidence of colon cancer is getting higher and higher, but many friends lack knowledge about colon cancer. The best way to detect it is to check it regularly. What are the diagnostic methods for colon cancer? Let's take a look at the introduction below.

What are the diagnostic methods for colon cancer? The diagnostic methods for colon cancer are introduced as follows:

1. Sigmoidoscopy: This examination is suitable for patients whose tumors are located at a higher position and cannot be palpated by digital palpation, or for patients whose tumors can be palpated by digital palpation but have no preoperative pathological diagnosis. In this case, a tissue biopsy should be taken to confirm the diagnosis to avoid missed diagnosis or misdiagnosis.

2. Double contrast enema: Barium or air-barium double enema is an indispensable clinical examination for colon cancer. Its purpose is to observe the overall shape of the large intestine and whether there are multiple polyps and multiple cancers.

3. Endoscopic examination: Patients with blood in stool or changes in bowel habits who do not show any abnormalities during rectal examination should undergo routine sigmoid colon or fiber colonoscopy.

4. Serum carcinoembryonic antigen (CEA) test: It is not specific for detecting and diagnosing colon cancer, but it is helpful for estimating prognosis, monitoring efficacy and recurrence, especially for those with liver metastasis.

5. CT or MRI examination: mainly used to understand the extent of tumor infiltration into the intestine and whether there is local lymph node or distant organ metastasis. It can be used for preoperative staging and postoperative review.

Traditional Chinese medicine is the most important thing that cannot be ignored. It can improve symptoms, enhance the body's disease resistance, and reduce the side effects of radiotherapy and chemotherapy. Some traditional Chinese medicines have direct anti-cancer effects, such as Hedyotis diffusa, Scutellaria barbata, Trichosanthes kirilowii, Solanum nigrum, etc. When taking medicine, both syndrome differentiation and disease differentiation can be considered, and medicines that can clear away heat and detoxify, promote blood circulation, nourish yin and blood, remove phlegm and disperse knots, and regulate the spleen and stomach can be added.

Surgical treatment is one of the main treatment methods at present, and its effect is still relatively ideal for the middle and late stages, but it requires the removal of intestinal tissue, which requires a certain professional hospital to avoid danger.
