Beware of early signs of gastric cancer

Gastric cancer is a very common malignant tumor disease in the human body with a high incidence rate. my country is a high-incidence area of ​​gastric cancer, and tens of thousands of people die from gastric cancer every year. Experts remind that if early symptoms of gastric cancer appear, you must receive treatment in time.

Early symptoms of gastric cancer :

Early gastric cancer often has no obvious symptoms, and by the time patients seek medical treatment on their own, most are already in the middle or late stages. It is fortunate if one can seek medical treatment in the early or late stages. The overall 5-year survival rate of gastric cancer is 8% to 11%. Currently, the radical surgery rate for early gastric cancer is 90% to 100%, and the 5-year survival rate after surgery is 90% to 99%.

Stomach pain Most gastric cancer patients have stomach pain symptoms in the early stage of the disease. At first, they only feel upper abdominal discomfort or a feeling of bloating and heaviness, and sometimes a dull pain in the heart. It is often mistaken for gastritis or ulcer disease and is treated. The symptoms may be temporarily relieved. If the lesion occurs in the gastric antrum, changes in duodenal function and rhythmic pain may occur, similar to symptoms of ulcer disease. These symptoms are often ignored until the disease progresses and persistent pain or even black stools or vomiting blood occurs. By this time, the cancer is often in the late stage and the chance of cure is lost. Therefore, people must be alert to stomach pain, a common and non-specific early symptom of gastric cancer, and seek medical attention in time.

Loss of appetite, weight loss, and fatigue are also a group of common but non-specific early symptoms of gastric cancer.

Loss of appetite may be an early symptom of gastric cancer and is not accompanied by stomach pain. If it occurs at the same time as stomach pain and hepatitis can be ruled out, it should be taken seriously. Some patients automatically limit their daily diet due to abdominal distension and belching after eating, resulting in weight loss, emaciation and fatigue.

Nausea and vomiting Early symptoms of gastric cancer may include a feeling of fullness after eating accompanied by mild nausea. Cardiac tumors may initially cause eating difficulties, which gradually progress to dysphagia and food reflux. Further progression of gastric antral cancer may cause vomiting due to pyloric obstruction. This symptom of blood in the stool may appear in the early stages of gastric cancer. A small amount of gastric bleeding is manifested by positive occult blood in the stool. When the amount of bleeding is large, vomiting blood and black stools may occur. Elderly people who do not have stomach problems should be more alert to the possibility of stomach cancer if they have black stools.

Experts tell us: In addition to the above symptoms, diarrhea, constipation, discomfort in the lower stomach, deep tenderness when pressing the upper abdomen and mild muscle tension can also be regarded as early symptoms of gastric cancer.
