Can early gastric cancer be cured? More than 70% of early gastric cancer patients have no obvious symptoms. As the disease develops, non-specific symptoms similar to gastritis or gastric ulcer may gradually appear, including upper abdominal fullness and distension or hidden pain, acidity, belching, nausea, occasional vomiting, loss of appetite, indigestion, black stool, etc. As early gastric cancer is not easy to be detected and middle and late gastric cancer, surgery and radiotherapy can no longer control its spread and metastasis, resulting in a very low survival rate of gastric cancer patients. In China, about 170,000 people die of gastric cancer every year, accounting for about 1/4 of all malignant tumor deaths, and the average life expectancy of patients with advanced gastric cancer is only 13 months. Generally speaking, gastric cancer is divided into five categories according to the location of occurrence, including gastric lesser curvature, greater curvature, pylorus, cardia and gastric body cancer. The 5-year survival rate of gastric cancer is 20% for the lesser curvature, 0% for the greater curvature, 19.3% for the pylorus, 4.3% for the cardia, and 16.6% for the body of the stomach. The average survival period for patients treated with surgery and radiotherapy was 13 months. Symptoms of progressive gastric cancer (i.e. middle and advanced gastric cancer) are seen as pain in the stomach area, often biting, not obviously related to eating, or similar to peptic ulcer pain, which can be relieved after eating. Upper abdominal fullness, heaviness, anorexia, abdominal pain, nausea, vomiting, diarrhea, emaciation, anemia, edema, fever, etc. Cardia cancer mainly manifests as discomfort under the saber, pain or pain behind the sternum, accompanied by the feeling of obstruction in eating or difficulty in swallowing; cancer of the fundus and subcardia often has no obvious symptoms until the tumor is huge and necrotic ulceration causes upper gastrointestinal bleeding, or the tumor infiltration extends to the pancreatic orifice causing difficulty in swallowing; cancer of the gastric body is more common in the distended type, and the pain and discomfort appear later; cancer of the small curvature of the gastric sinus is most common in the ulcerated type. When the tumor extends to the pylorus, it can cause nausea, vomiting and other symptoms of pylorus obstruction. If the cancer spreads, it may cause ascites, hepatomegaly, jaundice and metastasis of lung, brain, heart, prostate, ovary and bone marrow, etc., and the corresponding symptoms may appear. The above is the introduction of “can early gastric cancer be cured”. For people who are related to the causative factors of gastric cancer, it is recommended to take preventive measures against gastric cancer.
