Early gastric cancer can cause acidity, bloating, eructation and increased anal discharge. These symptoms are not the basis for the diagnosis of stomach cancer. In fact, stomach cancer is a disease that is difficult to be diagnosed by external symptoms and usually relies on clinical examination to determine. Early symptoms of gastric cancer include acid reflux, erratic reflux, heartburn and bloating. These symptoms occur mainly because the gastric mucosa is destroyed during the development of gastric cancer, and the nerve endings under the mucosa are exposed and easily stimulated by the outside world. In addition, intestinal dysfunction will occur during the development of gastric cancer. These combined effects will lead to some of these symptoms. However, the diagnosis of gastric cancer is a serious and rigorous process. These symptoms are not specific. There are many diseases of the gastrointestinal tract that can present symptoms. Diseases such as esophagitis, gastritis, and enteritis can all show such symptoms. Relying on these symptoms cannot accurately determine gastric cancer. The diagnosis of gastric cancer must undergo necessary gastroscopy, biopsy and other examinations to be accurately judged. These symptoms described are actually some early symptoms of stomach cancer. If you experience acid reflux, eructation, burning sensation and bloating, you should go to the hospital for examination in time to make accurate judgment. In order to facilitate the early treatment of the disease and avoid delaying the disease.
