What are the symptoms of advanced gastric cancer? Is advanced gastric cancer harmful?

Advanced gastric cancer mainly refers to the phenomenon of metastasis and spread of cancer in the stomach, and has entered other organs or tissues, and is not sensitive to treatment effects such as surgery, radiotherapy and chemotherapy. The main symptoms of advanced gastric cancer are loss of appetite, nausea and vomiting, and anemia. If not treated in time, it will seriously affect the quality of life and even endanger life safety.

Gastric cancer is mainly a malignant tumor originating from the gastric mucosal epithelium. This disease ranks first among malignant tumors in my country. There are many reasons for the disease, which are directly related to diet structure, work pressure, Helicobacter pylori, etc. If it is in the early stage of gastric cancer, the possibility of cure is relatively high, but if it is not treated in time after the disease, it may develop into advanced gastric cancer. So what is advanced gastric cancer?
1. What is advanced gastric cancer ? Advanced gastric cancer refers to cancer that occurs in the stomach and has metastasized and spread, and has infiltrated other organs or tissues. It is not sensitive to treatments such as surgery, radiotherapy, and chemotherapy. Treatment is effective in a short period of time, but it is easy to relapse. The symptoms of advanced gastric cancer are mainly severe pain, severe loss of appetite, nausea, vomiting, and acid reflux. In addition, because of the inability to keep time normally, cachexia may occur, requiring intravenous high-nutrient injections.
2. Symptoms of advanced gastric cancer
1. Loss of appetite <br/>The most obvious symptom of gastric cancer in the late stage is loss of appetite. Because eating is affected, patients will experience weight loss, their bodies will become thinner and thinner, and they may also experience a certain degree of abdominal distension and belching.
2. Nausea and vomiting <br/>Nausea and vomiting are the most common symptoms of advanced gastric cancer. Because most gastric cancers are located in the pyloric antrum, pyloric obstruction is very common. Atypical early obstruction will cause bloating, nausea, and regurgitation after eating. Typical mechanical pyloric obstruction will cause gastric distension and vomiting. Most of the vomit is leftover food that has stayed in the stomach for too long, so it will have a sour and foul smell.
3. Anemia <br/>In the late stage of gastric cancer, eating will be affected, so weight loss will occur. Most of these patients will have symptoms of anemia and feel weak all over the body. If it is only mild anemia, it is usually not easy to detect.
3. Harms of advanced gastric cancer <br/>Gastric cancer in the advanced stage will seriously affect the quality of life. Most patients will experience persistent abdominal pain and even pyloric obstruction, which will make it impossible for them to eat normally. If the tumor metastasizes to distant sites, it will also cause corresponding metastatic symptoms. In addition, the cure rate of advanced gastric cancer will drop significantly. Even with comprehensive treatment, only a small number of patients can be cured, and the prognosis is poor.
