What is the incidence of gastric cancer in China? Gastric cancer is one of the most common malignant tumors in China, and the mortality rate ranks first among malignant tumors, with more than 400,000 new cases each year, with more men than women, and the ratio of men to women is about 2:1. The annual mortality rate is 20.93 per 100,000 population for men and 10.16 per 100,000 population for women, with the ratio of men to women being 2.5-3:1. Gastric cancer can occur at any age, mostly between 40-69 years old. What are the causes of gastric cancer? The causes of stomach cancer are not well understood and may be related to various factors, such as environmental factors, living habits, diet, genetic factors, etc. It is also related to chronic gastritis, gastric ulcer, gastric polyp and residual stomach. Early warning signs of gastric cancer? Occult pain, pain or change in pain pattern in the upper abdomen; feeling of fullness, acidity, belching, loss of appetite, nausea, burning in the stomach and diarrhea, black stool; over 50 years old, no history of stomach pain or gastric disease in the past, stomach symptoms appear within a short period of time. After recovering well from a major gastrectomy for a benign disease many years ago, you should go to the hospital for screening if you have recently experienced indigestion, epigastric pain, nausea, vomiting and black stools. Although there are various methods for stomach cancer screening, fiberoptic gastroscopy combined with pathological examination is the best method to detect and diagnose early gastric cancer; in recent years, painless gastroscopy has been widely used to reduce patients’ discomfort. Therefore, people who are at high risk of developing gastric cancer as mentioned above should undergo gastroscopy screening as early as possible in order to detect early lesions and treat them as early as possible. What are the treatment methods for gastric cancer? Currently, surgery is the main treatment and the only possible way to cure gastric cancer. Based on the traditional open surgery, the minimally invasive surgery developed in recent years has the advantages of small incision, less bleeding, less postoperative pain, quick recovery of gastrointestinal function, early getting out of bed and short hospitalization time. Other treatments include chemotherapy, radiation therapy, immunotherapy, Chinese herbal medicine, etc. The prognosis of gastric cancer is that the five-year survival rate of early gastric cancer (cancer infiltration is limited to the mucosal layer and submucosal layer) can be as high as 90% or more, while the five-year survival rate of progressive gastric cancer after radical resection generally ranges from 15% to 50%, depending on the degree of tumor infiltration, malignant degree and the degree of surgical cure. Therefore, early detection and early treatment are the only guarantee to improve the survival rate of gastric cancer. How to follow up after gastric cancer surgery? Generally, within 3 years after surgery, follow-up check-ups should be conducted once every 3 months; 3-5 years after surgery, follow-up check-ups should be conducted once every 6 months; after 5 years, follow-up check-ups should be conducted once a year until lifetime. Blood biochemical examination and tumor index examination should be performed in each review, and CT examination of chest and abdomen is also recommended, and gastroscopy is generally recommended once a year. What can be eaten after gastric cancer surgery? How to eat? After being discharged from hospital, gastric cancer patients should eat easily digestible food that is well cooked and with less residue. There are no obvious restrictions on the types of food, avoiding foods that are not fresh and spicy, and emphasizing the principle of eating less and more meals.
