Three major diagnostic methods for gastric cancer

Gastric cancer is a type of cancer that occurs in the stomach. In my country, the incidence of gastric cancer ranks first among all types of cancer. Gastric cancer has gradually become a killer of young men and women in urban life, and gastric cancer has attracted more and more attention. So if you suspect that you may have gastric cancer and go to a regular hospital for diagnosis, how many diagnostic methods does the relevant hospital have?

1. X-ray diagnosis

X-ray diagnosis must be closely combined with clinical practice, and suspicious lesions must be repeatedly examined and followed up closely. Negative X-ray examinations cannot rule out the existence of lesions. Barium contrast has promoted the development of "gastrointestinal motility", which is the study of the motor function of the gastrointestinal tract and the series of technical changes that occur in barium contrast. It is the key to exerting the advantages of air-barium double contrast contrast. It has important diagnostic value, especially for the detection of early tumors.

2. Endoscopic examination

This is the most important means of diagnosing early gastric cancer. The endoscopes currently used are generally electronic endoscopes, which have a slender body and good curvature, and can observe gastric lesions very clearly. During the examination, the doctor's experience and conscientiousness are very important. Do not overemphasize the length of the examination time. Although a short examination time can reduce the patient's pain and is also welcomed and praised by the patient, if the time is too short, it is often impossible to make subtle observations of various parts of the stomach, and major lesions are left behind, which is the greatest harm to the patient. Sometimes when the endoscope is inserted into the stomach, at first glance, there seems to be no special lesions, but after a closer look, lesions are found. For any suspicious lesions, a living tissue should be clamped for pathological section examination.

3. Use dynamic CT

Dynamic CT can show the multi-layer structure of the gastric wall and the destruction of the mucosal layer, thus diagnosing early gastric cancer.

Symptoms of advanced gastric cancer include:

1. Enlarged lymph nodes in the greater and lesser curvatures of the stomach and around the abdominal aorta

2. A mass in the gastric cavity with irregular shape and rough surface, which may be accompanied by ulcers of varying depths.

3. When the tumor infiltrates outward, the fat layer around the stomach becomes thinner and affects adjacent organs such as the liver and pancreas.

4. Thickening of the gastric wall, but thickening of the gastric wall is not a specific manifestation of gastric cancer and needs to be differentiated from gastric lymphoma, chronic hypertrophic gastritis, etc.

Through the above explanation, we know the three major diagnostic methods for gastric cancer in relevant hospitals. If we go to relevant hospitals for diagnosis, we will have some understanding of some diagnostic processes. Finally, we remind readers: For diagnosis and treatment of gastric cancer, please go to a regular hospital. This article is for reference only.
