How to diagnose gastric cancer? There are five ways to check

Gastric cancer is a very serious disease that can cause patients to lose their lives, so timely examination and treatment are very important. To diagnose gastric cancer, you must do a routine blood test, gastric juice analysis, X-ray barium meal examination, and gastroscopy. Patients should also pay attention to changes in their bodies in life and diagnose problems in a timely manner so that better treatment can be achieved.

There are many types of cancer, and cancer can occur in different parts of the body, so it is very important to use the correct treatment method according to your actual situation. Do a physical examination and clearly determine whether the disease is serious so that you can choose the appropriate treatment method. Here I will introduce to you how to diagnose gastric cancer.
1. Routine blood test <br/>Many gastric cancer patients have iron deficiency anemia, which may be caused by prolonged blood loss. They may also develop pernicious anemia, just like megaloblastic anemia. If the patient has a persistent positive result in the fecal occult blood test, it may be caused by gastric cancer and has good diagnostic significance.
2. Gastric juice analysis <br/>Gastric cancer patients may have low gastric acid secretion or abnormalities in the gastric acid area, but there may be overlap with normal people, so this diagnostic method is not listed as a routine examination, but it is also a good diagnostic method.
3. Tumor marker detection <br/>Generally, the specificity of gastric cancer markers is not very strong, and they are not very useful for the diagnosis of serum carcinoembryonic antigen. Many gastric cancer patients have elevated CEA in their gastric juice, but this is the same as chronic atrophic gastritis, so they will be confused with each other and delay the diagnosis, making the disease more and more serious.
4. X-ray barium meal examination <br/>The diagnostic value of various examination methods is very high. Compression method and air-barium double contrast method can be used for detection. High-density barium powder can be used to show the structure of the mucosa in detail, and even some tiny lesions can be discovered.
5. Gastroscopy <br/>This is also a very effective way to detect gastric cancer. An experienced doctor can make a judgment of more than 90% after the examination. It is necessary to extract a biopsy specimen and then conduct effective testing. It is more meaningful to use gastroscopy for patients with early gastric cancer. During the endoscopic examination, it may be found that the local mucosa is granular, with small pieces of discolored mucosa or slight changes in the local mucosa. A biopsy is needed to estimate the size of the cancer. If it is less than one centimeter, it is a small gastric cancer, and if it is less than 0.5 centimeters, it is a micro gastric cancer.
Gastric cancer is the most common malignant tumor of the digestive system. There will not be any obvious changes in the early stage, and patients usually cannot detect it. As the disease becomes more and more serious, obvious symptoms will appear when the overall condition and gastric function are affected. Therefore, it is important to go to the hospital regularly for a comprehensive check-up.
