Stomach cancer has a high incidence in China, and the mortality rate of stomach cancer is the first among malignant tumors, in addition, the incidence rate of men is higher than that of women. People in urban areas have irregular meals, which are highlighted in several aspects. Because of the traffic problem, they often eat late for dinner. In addition, in the past few years, people like to eat heavy oil and spicy food, such as similar to boiled fish, crawfish and so on, various types of gastric disease more and more.
For stomach problems, many people feel that it is a small matter, at most is tolerated. But in fact, it is this kind of laxity that makes minor diseases become major diseases and miss the best time. Even for stomach cancer, as long as it is detected early, the survival rate through surgery is still very high. Only that many people just don’t pay attention to it. Before the arrival of stomach cancer, there are actually many warning signs in the body. The key is whether you are alerted or not. Today, we would like to share with you several signs before the arrival of early gastric cancer.
Symptom 1: Upper abdominal pain and discomfort
This is the most common initial symptom of gastric cancer, about 80% of patients have this symptom, similar to indigestion, such as abdominal pain, which is mild and irregular at the beginning, but cannot be relieved after eating and gradually worsens, and can be vague or dull pain. Some of them can have rhythmic pain, especially sinus gastric cancer, which can be relieved by eating or taking medicine.
Symptom 2: Loss of appetite or loss of appetite
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 pain.
Warm tip: Anorexia of unknown cause is probably the initial symptom of early gastric cancer, which needs attention. Patients with early gastric cancer usually have no obvious positive signs, and most of them only have deep pressure pain in the upper abdomen in addition to weakness.
Symptom 3: Wasting and weakness
There is no obvious specific early symptom of gastric cancer, and most patients often seek medical treatment for wasting. The energy consumption and metabolic disorder caused by tumor proliferation can cause malnutrition, which can lead to rapid and unexplained wasting and weight loss.
Correct approach: If accompanied with symptoms such as epigastric pain, vigilance should be started.
Symptom 4: Fixed mass
There is no obvious special sign in early stage of gastric cancer, but a lump can be found in the upper abdomen during the progressive stage with careful observation. The mass is mostly located in the upper abdomen to the right of the gastric sinus, with hard texture, unsmooth surface and fixed position, and painful when pressed.
Symptom 5: Nausea, acid reflux and vomiting
Nausea is most obvious when the gastritis lesion of stomach cancer patients is located in the pylorus at the gastric outlet. If the gastric outlet is completely blocked, a sour or egg smelly odor will be belched out, or vomiting will occur, and the vomit is mostly persistent food and gastric juice.
Symptom 6: Abdominal distension after eating
If patients with stomach cancer have this symptom in early stage of stomach cancer, they will have a burning, noisy and full feeling in the abdomen, especially after meals, and the symptom will become more and more aggravated as the disease develops.
Warm tip: These symptoms should be distinguished from indigestion and chronic gastritis. Indigestion often has a history of careless eating and binge drinking, while chronic gastritis often has a history of recurrent episodes.
Symptom 7: Vomiting blood and black stool
This is a more serious special manifestation. Generally, in early stage of gastric cancer, the cancer in the body will destroy small blood vessels, which will lead to the symptom of occult blood in stool, that is, although the appearance of stool is normal, blood cells can be found in the stool. If the larger blood vessels are invaded in the early stage, it will cause vomiting blood and the stool will become black like tar.
Correct: The occult blood and black stool of gastric cancer are persistent and persistent. In contrast, bleeding caused by gastric ulcer and duodenal ulcer is mostly intermittent and can be stopped with timely treatment.
A final piece of advice: the human body has many alarms. The key is whether you see the alarm when it goes off. If the alarm keeps ringing and you ignore it, it is useless to have more signs and it will not save your life.
