Early cancer screening of the digestive tract requires gastroscopy

Gastroenteroscopy is usually required for early cancer screening of the digestive tract. Gastroenteroscopy is currently the main method for early cancer screening of the digestive tract. Gastroenteroscopy allows doctors to directly observe the condition of the digestive tract mucosa, detect early tumors or polyps, and perform tissue biopsy to confirm diagnosis. In addition, gastroscopy can also perform some therapeutic operations, such as polypectomy, mucosal resection, etc. For some high-risk groups, such as older, family history of digestive tract tumors, long-term smoking and drinking, chronic atrophic gastritis and other diseases, it is particularly important to screen for early cancer of the digestive tract. These populations are at higher risk for gastrointestinal cancer, and gastroscopy can detect lesions early, improving cure rates and survival rates. For those who are unwilling or unable to tolerate gastroscopy, doctors may consider other tests, such as fecal occult blood tests, serum tumor markers, and imaging. However, the accuracy of these methods is relatively low, and some early lesions may be missed. It should be noted that early cancer screening of the digestive tract needs to be carried out under the guidance of a doctor, and the appropriate examination method should be selected according to individual circumstances, and follow-up treatment and follow-up should be carried out according to the doctor's recommendations. In addition, diet adjustment and bowel preparation should be paid attention to before gastroscopy to ensure smooth operation and accuracy of results. In short, gastroscopy is an important test method for early cancer screening of digestive tract, but it is not suitable for everyone. Under the guidance of doctors, selecting appropriate examination methods, and carrying out standardized treatment and follow-up are the keys to improve the cure rate and survival rate of early cancer of digestive tract.
