What is gastric cancer? A malignant tumor

Gastric cancer is a malignant tumor of the gastric mucosal epithelium. Changes in diet, increased work pressure, and Helicobacter pylori infection can easily lead to gastric cancer. There are no obvious symptoms in the early stage, or non-specific symptoms such as upper abdominal discomfort and belching may appear, which are often similar to the symptoms of chronic gastric diseases such as gastritis and gastric ulcer.

Cancer is a disease that still worries people in today's society, because with current medical technology, there is no absolute certainty that cancer can be cured, especially in the middle and late stages when the probability of cure is even lower. Gastric cancer is actually a particularly serious disease that causes great harm to the patient's body, but most patients do not have a correct understanding of gastric cancer. So what is gastric cancer?
Gastric cancer is a malignant tumor of the gastric mucosal epithelium. In my country, the possibility of the occurrence of various malignant tumors is very high. The incidence of gastric cancer actually varies greatly from region to region, and the highest is also very obvious. It is more likely to occur in people over 50 years old, and it is more common in men than in women.
Gastric cancer occurs at a younger age due to changes in diet, high pressure at work, Helicobacter pylori infection, etc. Gastric cancer can occur anywhere in the stomach, and it is very likely to occur in the antrum. Most gastric cancers are adenocarcinomas. In the early stages, there is no discomfort, or discomfort in the upper abdomen, hiccups, etc., which are similar to the symptoms of gastritis. Chronic gastric diseases such as gastric ulcers are easily ignored by people. At present, the early diagnosis rate of gastric cancer is also relatively poor.
The prognosis of gastric cancer is closely related to the time of diagnosis and treatment. The treatment effects of early gastric cancer and advanced gastric cancer vary greatly. Most early gastric cancers can be cured by endoscopic resection of the lesions, and the 5-year survival rate has reached more than 90%. However, according to the latest statistics from the Chinese Gastrointestinal Surgery Alliance, many gastric cancer patients in China die due to late diagnosis, which has become an important reason for the loss of treatment opportunities.
As far as current medical methods are concerned, gastroscopy is the gold standard for gastric cancer diagnosis and the most effective method for gastric cancer screening. With the rapid development of medical technology, comfortable gastroscopy without intubation has become popular, which can achieve painless and accurate gastroscopy, and its examination accuracy is consistent with that of electronic gastroscopy.
