Generally speaking, the occurrence of gastric cancer is the result of long-term comprehensive action of many factors, which may not be caused by one factor, but related to many factors, such as environment, diet, family inheritance and so on.
The general symptoms of gastric cancer can be divided into the following points:
(1) Abdominal distension discomfort
The early symptom of gastric cancer may be fullness and discomfort in the upper abdomen, which is usually the early symptom of gastric cancer in the elderly. Patients with gastric cancer may sometimes be accompanied by pantothenic acid, nausea, vomiting and belching. Symptoms usually appear in the absence of obvious incentives, mostly when they are quiet, and disappear when activities and spirits are distracted. Diet adjustment does not help much.
(2) Upper abdominal pain
Upper abdominal pain, the pain pattern of some patients with gastric cancer is similar to that of peptic ulcer, while the pain of the elderly is relatively dull, mainly manifested as abdominal distension. If some patients and friends often have intermittent dull pain, or the interval of pain is getting shorter and shorter, getting worse and lasting, you should be vigilant at this time, because this may be one of the early symptoms of gastric cancer.
(3) Loss of appetite, emaciation and fatigue
Some elderly patients with gastric cancer may have obvious symptoms such as loss of appetite, weight loss and general fatigue. The causes of these symptoms are unknown and need to be examined and diagnosed in the hospital. If accompanied by epigastric pain, hepatitis can be ruled out and attention should be paid to it, which may also be the main symptom of early gastric cancer.
(4) Black stool or fecal occult blood is positive.
There are many reasons why the stool is black. If you have black stool without taking blood tofu and bismuth, you should go to the hospital for examination and treatment as soon as possible.
(5) The original pain law of chronic gastropathy has changed.
When new discomfort symptoms appear or the original pain law changes, or the effect of taking medicine is not obvious, you should also go to the hospital for examination in time.
(6) signs
At the beginning of the disease, most patients with gastric cancer have no obvious signs, only deep tenderness in the upper abdomen or slight muscle tension enhancement.
Gastric cancer is a very common malignant tumor in digestive system. To prevent the occurrence of gastric cancer, we must pay attention to its early symptoms. Because some patients will mistake stomach pain, loss of appetite, nausea and other symptoms for gastritis or other stomach diseases, they can't bear to see a doctor again. When it was discovered, the illness was in the advanced stage, which delayed the appropriate treatment opportunity and caused great regret.
The above content is about some symptoms of early gastric cancer. In daily life, it is suggested that everyone pay attention to diet, reasonably match and balance, maintain good work and rest habits, eat less cold or spicy food, and try to improve their physical fitness. If patients with chronic stomach diseases need timely treatment, they should be examined regularly to eliminate precancerous lesions and prevent gastric cancer. In addition, the incidence rate of people with a family history of cancer is generally much higher than that of ordinary people, so we should pay attention to regular physical examination.
