Three common methods for diagnosing colon cancer

With the advancement of modern medical technology, the diagnosis of colon cancer has been greatly improved, which can help doctors diagnose colon cancer more accurately, which is very beneficial to patients with colon cancer. So what are the common diagnosis methods for colon cancer ? Let's talk about the common diagnosis methods for colon cancer.

In general, the common diagnosis methods of colon cancer are:

1. Sigmoidoscopy and fiber colonoscopy are common methods for diagnosing colon cancer. Although the sigmoidoscope is 25 cm long, 75% of colorectal cancers are within the scope of the sigmoidoscope. Microscopic examination can not only detect tumors, but also observe their size, location, and local infiltration range. Sigmoidoscopy can be used to take tissue 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 diagnosing colon cancer.

2. The diagnosis of colon cancer can also be done by anal digital examination and rectal endoscopy to check for rectal polyps, rectal cancer, internal hemorrhoids or other lesions for identification.

3. Currently, there is still a lack of feasible plans for large-scale population-wide prevention and control of colon cancer. The only way is to promptly select appropriate examination methods when encountering the above-mentioned suspicious signs of colon cancer and make an early diagnosis of colon cancer, especially when encountering a positive fecal occult blood test. It is imperative to further identify the cause and provide timely treatment.
