Common diagnostic methods for rectal tumors

Intestinal tumors are common malignant tumors. They are a general term for rectal tumors and colon tumors, and they often occur in middle-aged and elderly people. So how is rectal tumor diagnosed in medicine?

Experts point out that there are mainly the following methods for diagnosing rectal tumors:

1. Rectal and anal digital examination. In China, more than 50% of rectal tumors occur in the rectum, and 80% of rectal tumors are in the middle and low positions, which can be detected by rectal and anal digital examination.

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

3. Barium enema X-ray examination: Patients with lesions in the upper sigmoid colon or higher should undergo 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.

4. The most definite examination method is colonoscopy, commonly known as colonoscopy, which is divided into fiber colonoscopy and sigmoidoscopy.
