The early symptoms of stomach cancer are not much different from those of common stomach diseases, and heartburn and acid reflux are the most easily ignored signs of stomach cancer. What are the warnings given by stomach cancer before it comes? Heartburn and acid reflux Heartburn generally refers to the lower part of the sternum, which is often referred to as the “heart pit”, like a burning sensation. This is mainly caused by food from the stomach “running” into the esophagus. The stomach secretes gastric acid, so everything in the stomach is acidic, while the esophagus is alkaline. When the acidic substances “run” into the esophagus, it will corrode the mucous membrane of the esophagus, just like a fire burning in the heart pit, which is what we call heartburn. Upper abdominal discomfort and pain is also the most common initial symptom of gastric cancer, which is mainly manifested as a feeling of fullness or burning after eating, with recurrent episodes, the duration of which is not long and the symptoms are not so intense that it can be easily mistaken as indigestion or gastritis, leading to neglect. If some indigestion symptoms such as loss of appetite, nausea and vomiting, acid reflux and belching occur repeatedly, you should also go to hospital in time to investigate whether it is stomach cancer. 57.5% of stomach cancer patients have loss of appetite in early stage and 57.2% have nausea and vomiting. 74.7% of stomach cancer patients have pain in upper abdomen in early stage. It is mild at first and then gradually worsens. Sometimes this pain is vague, sometimes it is intermittent dull pain. Some other patients have rhythmic pain (this kind of sinus cancer is more obvious), which will be relieved after eating or taking medicine; some elderly people have dull painful nerves and do not feel stomach pain thinking it is just bloating, which also needs to be beware of. The upper abdominal pain in the early stage of stomach cancer is often diagnosed as gastritis or gastric ulcer, so patients need to pay extra attention to it. Stomach cancer sign three, anemia Chiang’s Herb House Medical Center cautions pro: “There is another more hidden sign of stomach cancer, which we will not even associate with stomach disease, and that is anemia.” In people suffering from stomach cancer, the tumor destroys blood vessels causing stomach bleeding, and some people will have the symptom of vomiting blood, which is the main cause of anemia. Stomach cancer signs IV. Dark stool or bleeding stool In the case of eating pork liver, sweet potato, red heart dragon fruit, blood tofu or iron supplements, bleeding black or dark stool is very normal. However, if these conditions are excluded and black stools are produced, or even if the stools are directly bloody, the possibility of stomach cancer should be considered. Stomach cancer patients often have a small amount of bleeding in their intestines and stomachs, which can aggravate the disease if not taken seriously.
