Examination methods for confirming colon cancer

Correct medication guidance for colon cancer patients can help improve the rehabilitation effect of colon cancer patients. In daily life, it is necessary for colon cancer patients to use medication correctly. At the same time, they should also pay attention to the adverse reactions of colon cancer patients to drugs. Colon cancer patients should understand the common sense of colon cancer. There are many ways to diagnose colon cancer, so what are they?

Abdominal plain film examination and barium enema examination: Abdominal plain film examination is suitable for cases with acute intestinal obstruction; barium enema examination can show that the intestinal wall at the cancer site is stiff, with poor distensibility, weakened or disappeared peristalsis to the lesion, irregular or disappeared colon bag shape, narrow intestinal cavity, disordered, destroyed or disappeared mucosal folds, filling defects, etc. Barium-air double contrast radiography is more helpful in diagnosing pedunculated tumors in the colon.

Carcinoembryonic antigen test: This method of diagnosing colon cancer has little diagnostic value for early cases, but it is helpful for inferring prognosis and judging recurrence. It is worth mentioning that colon cancer is mainly adenocarcinoma, and the rest are mucinous adenocarcinoma and undifferentiated carcinoma. The gross morphology can be polyp-like, ulcerative, etc. Colon cancer can develop in a circular manner along the intestinal wall, spread up and down along the longitudinal diameter of the intestinal tube, or infiltrate into the deep layer of the intestinal wall. In addition to metastasis through lymphatic vessels and blood flow and local invasion, it can be implanted into the abdominal cavity or spread along sutures and incision surfaces. It is more common in middle-aged men, and those who have transformed from adenomatous polyps to cancer have a younger age of onset. Therefore, early diagnosis of colon cancer is more critical.

Anal digital examination and rectal endoscopy: used to check for rectal polyps, rectal cancer, internal hemorrhoids or other lesions.

Sigmoidoscopy and fiber colonoscopy: Although the sigmoidoscope is 25 cm long, 75% of colorectal cancers are within the scope of the sigmoidoscope. Microscopic examination can not only detect cancerous tumors, but also observe their size, location and local infiltration range. Through the sigmoidoscope, tissues can be taken for pathological examination. Skilled operators can insert the fiber colonoscope into the cecum and terminal ileum, and can also take photos. It is indeed an ideal method for diagnosing colon cancer.

Colon cancer is a common disease in life. Many people are not aware that colon cancer is a disease and treat it as other diseases. Colon cancer patients cannot receive timely treatment. The occurrence of colon cancer brings troubles to the healthy life of colon cancer patients. Therefore, we must start the treatment and care of colon cancer as soon as possible to keep the disease away from our lives as soon as possible.
