The reason why early symptoms of gastric cancer are not easy to detect is because its symptoms are similar to those of common digestive diseases, which may only include loss of appetite and abdominal discomfort, etc. These symptoms are easily confused with gastric diseases such as gastritis and gastric ulcer, which make people easily put down their guard. In China, most gastric cancer patients often already have more typical symptoms when they visit hospitals, by which time the cancer has already developed to the middle and late stages. To get the best time to treat gastric cancer depends largely on how much attention we pay to the early signs of gastric cancer, and recognizing the early symptoms of gastric cancer is helpful for prevention and treatment. The following are some early symptoms of gastric cancer, which should not be avoided and should be diagnosed and treated as early as possible. What can be the early symptoms of stomach cancer? 1. Bleeding: Stomach cancer has the symptom of bleeding in the early stage, but it is difficult for us to detect it, while in the late stage, the bleeding volume of stomach cancer patients will become very large. Individuals may have coffee-colored or dull red blood mixed with vomit, while a small amount of upper gastrointestinal bleeding can be detected by gastroscopy or fecal occult blood test. 2.Loss of appetite: Patients with early stage of stomach cancer have no desire to eat and are obviously anorexic. After a long time, they will lose weight and slowly lose weight, or become full and belching after eating, and abhor meat, which are more common symptoms of stomach cancer. What are the symptoms of stomach cancer? 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 abdominal pain. This is one of the reasons why we are paralyzed, thinking that old stomach disease is always like this, so we just let it hurt and do not check it or pay attention to it. However, if the nature and regularity of the original stomach pain has changed, we need to pay attention to it: for example, if the original stomach pain is always painful when you eat, but not when you sleep at night, if suddenly there is a continuous pain even when you sleep at night, such a change in pain habit and regularity. In short, patients with long-term gastric disease (especially male patients around 50 years old) should be alerted if the nature and pattern of epigastric pain has changed recently and there is no significant improvement after 2 to 3 months of systematic treatment, and should go to the hospital for relevant examination as soon as possible. 4. Sudden onset of abdominal discomfort that cannot be relieved without a history of gastric disease. These discomfort symptoms include stuffy stomach, loss of appetite, indigestion, accompanied by pantothenia, and mostly without causative factors, poor effect of oral medication, or sometimes good and bad, with symptoms characterized by progressive aggravation. Common gastric diseases often have obvious triggers before the onset, such as drinking, eating cold food, drinking cold drinks, etc. If there is no obvious trigger for stomach discomfort, the possibility of stomach cancer should be excluded; 5. Weight loss: early symptoms of stomach cancer may be manifested in obvious weight loss, because the tumor continuously competes with the body for nutrition during the growth process, and the patient’s weight is significantly reduced. Previous episodes of gastric disease have little effect on appetite, physical strength and weight, while gastric cancer can lead to loss of appetite, weakness and obvious weight loss, etc. The early symptoms of gastric cancer are very similar to those of digestive tract diseases, so if there are similar symptoms, it is recommended to run to the hospital more often for relevant screening. In this way, we can take precautions and add a “safety lock” to our health. It is common for patients to be labeled as gastritis, ulcer disease and indigestion by their family members and themselves in the early stage of gastric cancer, and miss the best time to treat gastric cancer. In addition, many people who do not have the foundation of gastric disease are afraid of gastroscopy and take some gastric medicine casually because of stomach discomfort, so that early gastric cancer becomes late.
