What are the methods for checking gastric cancer?

What are the methods for checking gastric cancer? I believe many people have this question. Gastric cancer is a cancer with a relatively high incidence. Data show that the incidence of gastric cancer has increased in recent years. There are generally no symptoms in the early stage, and most of them are in the middle and late stages after confirmation. Let us follow the experts to learn about the examination methods for gastric cancer .

1. Physical examination is one of the examination methods for gastric cancer. The doctor conducts a comprehensive physical examination on the patient to check whether the patient has obvious weight loss, jaundice (yellowing of the skin and eyes), and obvious abdominal distension; the doctor also performs a touch examination on the patient, such as touching the neck to determine whether there is obvious cervical lymph node metastasis; touching the abdomen to determine whether there is tenderness, obvious abdominal mass, enlargement of the liver and spleen, etc. Sometimes a digital rectal examination is also required to determine whether there is a mass in the anus, blood in the anus and rectum, etc. When judging whether there is intestinal obstruction, a stethoscope is needed to auscultate the abdomen.

2. Stool examination: If multiple stool examinations show positive occult blood, gastrointestinal tumors should be suspected and further examinations should be performed.

3. X-ray examination is also a method of examining gastric cancer. Barium contrast is the first choice and main method for examining gastrointestinal tumors, and is of great significance for the diagnosis of gastrointestinal tumors. X-ray diagnosis must be closely combined with clinical practice, and suspicious lesions must be repeatedly examined and closely followed up. Negative X-ray examinations cannot rule out the presence 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 giving full play to the advantages of air-barium double contrast contrast. It is especially of great diagnostic value for the detection of early gastric cancer tumors.

4. Gastroscopy. Among various examination methods, gastroscopy is recognized as the best method for diagnosing gastric cancer, especially in the diagnosis of early cancer. Gastroscopy is clear and can directly observe the lesions of the gastric mucosa, especially for bulging, swollen, and ulcerated lesions. Biopsy can be performed at the same time to quickly make a clear diagnosis, which has high use value. Gastroscopy is the most reliable method for screening gastric cancer. For the early detection of gastric cancer, gastroscopy is the internationally accepted method. Many people are afraid of gastroscopy, thinking that gastroscopy is very painful. Some patients do not undergo examinations in the early stages of upper gastrointestinal tumors, thus delaying the diagnosis. It is not until the late stage that they are diagnosed with cancer, which is too late.

5. CT examination is also one of the examination methods for gastric cancer. Generally speaking, CT examination is good at solid organs, but it is bad at hollow organs. As for gastric cancer, if CT is used to diagnose early gastric cancer, not to mention the need for special developer and high cost, its reliability is far inferior to gastrointestinal barium meal or gastroscopy; if it is used to diagnose advanced gastric cancer, if you want to know whether gastric cancer has metastasized to the liver or other organs, or to find lymph nodes where cancer has metastasized to the surrounding areas, then CT examination is of practical significance.
