Stomach cancer begins in the inner mucous membrane of the stomach, and cancer cells gradually penetrate the stomach wall and metastasize to surrounding lymph nodes. Furthermore, the cancer metastasizes to the abdominal cavity and body organs, eventually leading to death.
In the early stages of gastric cancer, there are no distinctive symptoms. In some cases, stomach cancer has no symptoms until it is quite advanced. The most common symptoms of gastric cancer patients include epigastric pain and discomfort, in addition to indigestion, stomach bloating, nausea, vomiting, loss of appetite, weight loss, hematemesis, melanoma, and anemia.

    The most ideal treatment for gastric cancer is to detect it at an early stage and perform radical gastrectomy. The common treatment for advanced gastric cancer is radical gastrectomy and adjuvant chemotherapies. When stomach cancer reaches stage 4, becoming a systemic disease, surgical resections cannot help a patient's survival.
As stomach cancer develops, it can block food from going down and cause intestinal obstruction. When stomach cancer is necrotic and blood vessels are exposed, bleeding occurs, which leads to anemia and, in severe cases, the patient falls into a state of shock, releasing black stools and showing symptoms of hematemesis. With necrosis of gastric cancer, peritonitis due to perforation of the stomach may be induced, and then the patient needs to be moved to an emergency room.

    It is very important for doctors to detect the disease before it further progresses, because early gastric cancer can be perfectly cured with curative surgery. In particular, sometimes, if it is detected at a very early stage, it is possible to remove only a portion of the stomach using an endoscope or laparoscopy. It is recommended that patients with non-specified upper gastrointestinal symptoms such as epigastric pain and indigestion, especially those whose symptoms persist even after receiving medical treatment, undergo a gastroscopy. Even if there are no symptoms, it is recommended for patients to have a gastroscopy every 1 to 2 years after reaching the age of 40.
