How to check for colon cancer

In order to have a clearer understanding of the condition of colon cancer patients, a comprehensive colon cancer examination should be carried out before receiving colon cancer treatment. Having a clear understanding of the severity of the disease is very beneficial for treatment. What are the main colon cancer examination methods? The following will tell you about the main colon cancer examination methods.

In general, the main methods of colon cancer screening are:

(I) X-ray examination is the main method for detecting colon cancer

1. Abdominal plain film examination: It is suitable for cases with acute intestinal obstruction. It can be seen that the colon above the obstruction site is inflated and swollen.

2. Barium enema examination: The intestinal wall at the site of cancer is rigid and poorly distensible, the peristalsis is weakened or disappears at the lesion, the colon bag is irregular or disappears, the intestinal cavity is narrow, the mucosal folds are disordered, destroyed or disappear, and there is a filling defect. Barium-air double contrast radiography is more helpful in diagnosing pedunculated tumors in the colon.

(ii) 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 cancer, but also observe its size, location and local infiltration range. Through the sigmoidoscope, tissue can be taken for pathological examination. Fiber colonoscopy can provide a higher diagnosis rate and has been widely used in China. 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 examining colon cancer.

(III) Carcinoembryonic antigen (CEA) test

It has little diagnostic value for early cases, but it is helpful in predicting prognosis and judging recurrence, and is also a relatively good method for examining colon cancer.

The above are the main methods of checking colon cancer, I hope it will be helpful to everyone. Once diagnosed with colon cancer, you must go to the hospital for active treatment in time to receive better treatment and effectively alleviate the condition.
