There are many ways to diagnose gastric cancer, and the most commonly used method is gastroscopy. Other methods can also be considered to diagnose whether a person has gastric cancer, such as X-ray examinations and CT examinations. Among them, CT examinations can also determine whether there is a metastasis of cancer cells?

Nowadays, medical technology is constantly developing, so when a person suffers from a certain disease, there are often multiple diagnostic methods to determine whether he or she has certain diseases. Among the many detection methods for these diseases, the most commonly used method is blood test. Can blood test detect gastric cancer?
1. Can blood tests detect gastric cancer? Although blood tests are necessary in the process of checking for gastric cancer, it does not mean that the results of blood tests can diagnose whether a person has gastric cancer. This is mainly because even if the results of blood tests show that the level of a certain tumor-related marker in the human body is constantly increasing, it still does not mean that the person has a certain cancer.
So in general, the results of blood tests can only be used as a basis for judgment, and cannot be a complete diagnosis. If you want to determine whether a person has stomach cancer, there are many tests that need to be done. Among the various examination methods, the best method is gastroscopy.
2. What are the methods for gastric cancer examination?
1. Gastroscopy <br/>Among the many ways to check for gastric cancer, the best way is gastroscopy. This is mainly because gastroscopy can most intuitively show the gastrointestinal condition of the patient, especially the pathological condition of the gastric mucosa is very clear. And the most important thing is that gastroscopy can also perform pathological biopsy at the same time, so a clear diagnosis can be obtained. However, it should be noted that gastroscopy is an invasive examination method, which may cause painful symptoms in the human body during the examination.
2. CT examination
CT examination is also a good way to detect gastric cancer, because this examination method can clearly show the specific condition of the human stomach wall and the growth range of cancer cells. It can also show whether gastric cancer has metastasized.
3. X-ray inspection
X-ray examination can also diagnose whether a person has gastric cancer. The X-ray results of gastric cancer in different parts of the body are also different.
