What are the diagnostic methods for rectal cancer

What are the diagnostic methods for rectal cancer? Most people should know the harm that rectal cancer brings to humans. It not only destroys the human body, but also causes great psychological distress and pressure. This disease should not be underestimated. So what are the diagnostic methods for rectal cancer? Let's discuss this issue with experts.

1. Pathological examination

Pathological examination is the fundamental basis for disease diagnosis.

2. Digital rectal examination

In the early stage of the disease, 70 to 79 percent of patients can feel a lump during rectal examination, which is bumpy and hard. In the late stage of the disease, a lump in the narrow intestinal cavity can be felt, and dirty pus and blood attached to feces appear on the fingertip.

3. B-ultrasound examination

This examination has only been implemented in recent years. It not only allows for intrarectal ultrasound, but can also promptly detect whether the disease has metastasized to the liver.

4. Rectoscopy

The shape, size, and location of the tumor can be observed under direct vision, and sometimes the tumor tissue can be directly taken for pathological examination.

5. Telomerase activity detection

Suitable for examining the extent of development of colorectal tumors.

6. MRI

This examination is performed from three different directions to examine the pelvis and can effectively show the changes of rectal cancer. Among them, the small field of view and the rectal coil can see the damage of the tumor to the mucosa and its underlying layer.

7. Barium enema contrast radiography

This examination can not only identify multiple cancer foci in the large intestine, but also rule them out. However, X-ray examinations do not show lesions in the rectum, which can easily lead patients to believe that there are no lesions.

Through the detailed introduction of the diagnostic methods of rectal cancer by experts, I believe that everyone should now have a corresponding understanding of the diagnosis of rectal cancer. The editor reminds everyone that when rectal cancer occurs, actively adopt the corresponding diagnostic methods to diagnose the disease as early as possible and give it treatment.
