Experts introduce two major colorectal cancer diagnosis methods

Colorectal cancer is a tumor disease with a very high mortality rate. Many patients delay treatment because they do not diagnose colorectal cancer in time. What are the common diagnostic methods for colorectal cancer ? Here are some common diagnostic methods for colorectal cancer.

In general, the common diagnosis methods for colorectal cancer are:

1. Laboratory examination: Some routine blood tests can help patients understand their physical condition and check whether they have symptoms of anemia. Routine blood tests can help patients understand whether they have anemia. Routine stool tests can help patients check whether they have red blood cells and pus cells. Fecal occult blood tests for colorectal cancer are often positive. This method is simple and easy to use and can be used as a preliminary screening method for colorectal cancer and a routine examination for colon diseases. For those with positive fecal occult blood tests, barium enema, x-ray examination and endoscopy should be performed. If the fecal occult blood test is negative and colorectal cancer is highly suspected clinically, the examination should be repeated or x-ray barium enema examination should be performed. This is one of the common diagnostic methods for colorectal cancer.

2. X-ray examination: This is also a common method for diagnosing colorectal cancer in medicine. It is very safe and the accuracy of the diagnostic results is also very high. Through barium enema examination, intestinal peristalsis, the shape of the colon bag, whether the intestinal cavity is narrowed or dilated, whether there is a mass in the intestinal cavity, etc. can be observed. In the diagnosis of colorectal cancer, double contrast imaging of air barium enema helps to understand and exclude multiple primary cancers. However, it is useless for diagnosing rectal cancer and may even give people a false impression, especially for early or smaller lesions. Because when performing enema, the insertion of the anal canal often passes through or exceeds the lesion, the lesion cannot be shown in the x-ray, but people conclude that there is no lesion.
