Many people are confused about what the difference between gastritis and gastric cancer is. Some people mistake gastritis for gastric cancer and worry about it all day long, and the disease which is not serious will continue to deteriorate because of psychological effects; some people mistake gastric cancer for gastritis and do not take it seriously, thinking it is not serious, and miss the best time for treatment. It is recommended that patients who have doubts about the disease they are suffering from should go to professional hospitals for examination. So, what is the difference between gastritis and gastric cancer? The difference between gastritis and gastric cancer: Gastritis is a generic term for inflammation of gastric mucosa. It is a common disease and can be divided into two categories: acute and chronic. Acute gastritis is commonly known as simple and erosive. The former manifests as epigastric discomfort, pain, anorexia and nausea, vomiting; the latter has upper gastrointestinal bleeding as the main manifestation, with vomiting of blood and black stools. Chronic gastritis can usually be divided into superficial gastritis, atrophic gastritis and hypertrophic gastritis. Chronic gastritis has a prolonged course and most of them have no obvious symptoms and signs, usually only indigestion symptoms such as fullness after meals, acidity, belching, and irregular abdominal pain. The diagnosis depends mainly on gastroscopy and gastric mucosal biopsy. The disease is commonly seen in adults and can be irritated by many etiologies, such as improper diet, viral and bacterial infections, and drug stimulation. Gastritis can be easily corrected and improved. As long as you get rid of some bad eating habits, actively improve your life routine and rhythm, pay attention to your diet, or cooperate with some medicines for gastritis, you will be cured soon. More than 70% of early gastric cancer have no obvious symptoms, but as the disease develops, non-specific symptoms similar to gastritis or gastric ulcer may gradually appear, including upper abdominal fullness and discomfort or hidden pain, acidity, belching, nausea, occasional vomiting, loss of appetite, indigestion, black stool, etc. black stool, etc. Symptoms of progressive gastric cancer (i.e. middle and advanced gastric cancer) include pain in the stomach area, which is often biting in nature and not obviously related to eating, or similar to peptic ulcer pain, which can be relieved after eating. Upper abdominal fullness, heaviness, anorexia, abdominal pain, nausea, vomiting, diarrhea, emaciation, anemia, edema, fever, etc. Cardia cancer mainly manifests as discomfort under the saber, pain or pain behind the sternum, accompanied by the feeling of obstruction in eating or difficulty in swallowing; cancer of the fundus and subcardia often has no obvious symptoms until the tumor is huge and necrosis and ulceration cause bleeding in the upper gastrointestinal tract, or when the tumor infiltration extends to the cardia causing difficulty in swallowing; cancer of the body of the stomach is more common in the distended type, and the pain and discomfort appear later; cancer of the less curved side of the gastric sinus is most common in the ulcerated type. When the tumor extends to the pylorus, it can cause nausea, vomiting and other symptoms of pylorus obstruction. If similar symptoms occur, it is recommended to go to a professional hospital for barium X-ray, gastroscopy, ultrasound and other examinations to have an understanding of your physical condition.
