Explain to everyone how to diagnose colorectal cancer

Before treating colorectal cancer, patients must first be diagnosed with colorectal cancer. In addition to further confirming colorectal cancer, it is more important to have a clear understanding of the patient's condition, which is crucial for the correct treatment of colorectal cancer. So how should colorectal cancer be diagnosed ? The following will tell you about the diagnosis method of colorectal cancer.

In general, bowel cancer is diagnosed by:

1. Stool examination: Although the fecal occult blood test is not specific for the diagnosis of colorectal cancer, the method is simple and easy to perform. It can be used as a screening method and may provide clues for early diagnosis.

2. Barium enema X-ray examination: For patients with lesions in the upper sigmoid colon or higher, the diagnosis of colorectal cancer requires an X-ray barium enema examination. Ordinary barium enema X-ray examinations are prone to miss small rectal tumors. It is best to use air-barium double contrast, which can improve the accuracy of radiological diagnosis and show the location and range of the cancer.

3. Rectal and anal digital examination: More than 50% of rectal tumors occur in the rectum, and 80% of rectal tumors are in the middle and low positions. Rectal and anal digital examination can detect them, which is a good method for diagnosing colorectal cancer.

The above is the diagnosis method of colorectal cancer. I hope reading this article will be helpful to everyone. Once diagnosed with colorectal cancer, you must go to the hospital immediately and actively face treatment so that you can receive better treatment and effectively alleviate the condition.
