The first symptom is abdominal pain. Because early gastric cancer can cause inflammation to penetrate the serosa, invade the pancreas or transverse mesocolon, thus invading our abdomen and causing pain. This kind of pain is more intense and unbearable. Never take painkillers at will, because painkillers will cover up your pain and paralyze your nerves, so you can't judge the root of the problem well.
The second symptom is loss of appetite and obvious emaciation. Because patients with gastric cancer will absorb a lot of tumor toxins, which will make people lose appetite and lead to a series of problems such as anemia. Therefore, if you find that you have lost a lot of weight in a short time and have no appetite, you should go to the hospital to check if there is something wrong with your stomach.
The third symptom is hematemesis and black stool. This situation is a bit dangerous, after all, vomiting blood is a particularly dangerous situation. Then, if you find that your stool is black within a period of time, you must see a doctor in time.
Before the formation of gastric cancer, the body will give us many hints. Please don't take it lightly, because many patients can be cured if they cooperate with doctors in radiotherapy and chemotherapy, but if you have noticed these problems and don't pay attention to them, it will be the end of the game when you carefully check them, so that even doctors can't return to heaven.
