Gastric cancer is a malignant tumor originating from the epithelium of gastric mucosa, accounting for the 3rd place of all malignant tumors, the first place of digestive tract malignant tumors, and 95% of gastric malignant tumors. It can be seen that gastric cancer is a common disease threatening human health. Early stage gastric cancer is mostly asymptomatic or has only slight symptoms. When the clinical symptoms are obvious, the disease is already in advanced stage. Therefore, we should be very alert to the early symptoms of stomach cancer to avoid delaying the diagnosis and treatment. Symptoms and signs of gastric cancer Early manifestation. Upper abdominal discomfort is the most common initial symptom of gastric cancer, and about 80% of patients have this symptom, which is similar to indigestion. If abdominal pain occurs, it is generally light and irregular, and cannot be relieved after eating. These symptoms are often not taken seriously by patients and are easily mistaken for gastritis or ulcer disease when seeking medical attention. Therefore, middle-aged patients with the following conditions should be given further examination to avoid missing the diagnosis: ① No previous history of gastric disease, but recently developed unexplained epigastric discomfort or pain, which is ineffective after treatment; ② Previous history of gastric ulcer, and recently the regularity of epigastric pain has changed, and the degree is getting worse. If the symptoms are relieved, but there is another episode within a short period of time, the possibility of gastric cancer should also be considered and further examination should be conducted in time. Nearly 50% of gastric cancer patients have obvious symptoms of loss of appetite or loss of appetite, and some of them restrict eating on their own because too much food will cause abdominal distension or pain. Unexplained anorexia and weight loss are probably the initial symptoms of early gastric cancer, which need to be taken seriously. Patients with early gastric cancer usually have no obvious positive signs, and most of them only have deep pressure pain in the upper abdomen in addition to weak general condition. Late stage manifestation. When gastric cancer develops and expands, especially when the infiltration penetrates the plasma membrane and invades the pancreas, continuous severe pain may appear and radiates to the lower back. The absorption of toxins from the cancer can make the patient become increasingly thin, weak and anemic, and finally manifest as cachexia. When cancer grows up, obstruction symptoms may appear. Cancer of cardia or fundus may cause difficulty in swallowing, while cancer of gastric sinus may cause pyloric obstruction, and lumps may be found in the abdomen. When ulcers are formed on the surface of the cancer, blood vomiting and black stool will appear. As for metastases such as anterior rectal masses, umbilical masses, enlarged supraclavicular lymph nodes and the appearance of ascites, they are more evidence of advanced gastric cancer. 5-year overall survival is the gold standard for comparing gastric cancer treatment Surgical resection is still the only option to eradicate early gastric cancer and the main means to treat gastric cancer. For a long time, due to the late detection of gastric cancer, most of them are late stage tumors, the efficacy of surgery is poor, and the 5-year survival rate after surgery has been maintained at about 30%. Therefore, it is necessary to enhance the attention to the symptoms of early gastric cancer and the monitoring of high-risk groups to improve the detection rate of early gastric cancer. The knowledge content related to the surgical treatment of gastric cancer needs to be understood. The degree of invasion of gastric wall, the extent of lymph node involvement, the characteristics of tumor cells and the tumor growth pattern of gastric cancer patients before surgery all depend on the five-year survival rate of patients. Early gastric cancer only involves the mucosal layer or submucosal layer, and the prognosis is good, and the five-year survival rate after surgery is as high as 90%. If the tumor has involved the muscular layer, the five-year survival rate is significantly lower. If the mass appears in the form of mass, the resection rate is high; if the mass is diffuse, the prognosis is poor; if the tumor has reached the plasma layer and there is lymphatic metastasis, the prognosis is poor. For a kind of radical gastrectomy for gastric cancer, this surgical resection can only cut off the surface tumor, but not the millions of capillaries (the root of tumor) below the tumor, so the surgery can only eliminate the surface tumor, not cure the tumor, and may also accelerate the recurrence and metastasis of the tumor. It may also leave unimaginable after-effects of surgery. To prolong the survival, the follow-up treatment of surgery is important. Under the doctor’s suggestion, chemotherapy means will be carried out, together with the use of Chinese herbal medicine. Using Chinese herbal medicine will not produce any harm and toxic side effects to the body, and can also reduce the harm of western medicine to the body, and can also prevent recurrence and metastasis, with unexpected effects, however, this also varies from person to person, and not all patients are suitable for this follow-up treatment method.
