Facts tell us that early symptoms of gastric cancer are not easy to detect, and its symptoms are similar to those of common digestive diseases, which may only include loss of appetite and abdominal discomfort, etc. These symptoms are very easy to be confused with gastric diseases such as gastritis and gastric ulcer, so people may not think that early gastric cancer may also have similar symptoms. When most gastric cancer patients in China visit hospitals, they often already have more serious symptoms, by which time the cancer has 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 can be 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? Bleeding and positive stool occult blood test Stomach cancer can have the symptom of bleeding in the early stage, while in the advanced stage, the bleeding volume of stomach cancer patients will become very large. Individuals may have coffee-colored or dull-red blood mixed with vomit, and a small amount of bleeding is often difficult to detect without obvious symptoms. 2. Loss of appetite Early stage of stomach cancer patients have no desire to eat, obvious anorexia, or fullness and belching after eating, and aversion to meat are relatively common 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 of bloating or abdominal pain caused by excessive eating after stomach peristalsis becomes poor. After a long time, they will lose weight and slowly lose weight. 3. The regularity and change of pain nature of “old stomach disease” More than 80% of early gastric cancer patients will show symptoms of upper abdominal pain, which is one of the reasons for paralyzing us, thinking that old stomach disease is always like this, so let it hurt without checking or paying 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, if the nature and pattern of epigastric pain have changed recently in patients with long-term gastric disease (especially in male patients aged 40-50), and if there is no significant improvement after 2-3 months of regular treatment, they should be alerted and should go to the hospital for relevant examination as soon as possible. 4. Sudden onset of unrelieved abdominal discomfort without a history of gastric disease These discomfort symptoms include stuffy stomach, loss of appetite, indigestion, accompanied by acidity, and mostly without causative factors, poor effect of oral medication, or intermittent, with symptoms characterized by progressive aggravation. Common gastric diseases often have obvious triggers before the onset, such as drinking alcohol, 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 gastric cancer may be manifested in obvious weight loss, because the tumor keeps competing with the body for nutrition in the process of growth, and the patient’s weight drops significantly. 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. It is worth noting that these several symptoms are not specific, that is to say, if there are these manifestations, the possibility of cancer should be thought of, but it is not necessarily cancer, one should not take the right number and should not scare oneself, cancer may have one or several of these manifestations, but some manifestations are not equal to cancer, it should be correctly understood that the non-necessary relationship between diagnosis and disease diagnosis, the symptoms are to remind you to pay high attention, and the diagnosis needs to be re The diagnosis needs further examination in hospital to be clear. However, it is common to see patients in hospitals who are put on the hat of gastritis, ulcer disease or indigestion by their family members or themselves in the early stage of stomach cancer and miss the best time to treat stomach cancer; in addition, there are also many people who have no stomach disease foundation because they are afraid of gastroscopy and take some stomach medicine casually for stomach discomfort, resulting in early stomach cancer dragging into late stage, and it is a great pity that these people miss the opportunity of early detection and early treatment. The early symptoms of gastric cancer are similar to those of many other common digestive diseases, so if there are similar symptoms mentioned above, it is recommended to conduct relevant screening (especially for people with high risk of gastric cancer over 40), and the most accurate and effective method is gastroscopy, which can diagnose most diseases of the stomach at a glance and avoid “worrying” or “self-paralysis”. “The most accurate and effective method is gastroscopy.
