Gastric cancer is a common cancer, the mortality rate after lung cancer, liver cancer, colorectal cancer. However, because 80% of the non-specificity of symptoms of early gastric cancer, the diagnosis difficult, therefore, can not miss any clues cutting, especially following some misconceptions people may lose their vigilance against cancer.
One, stomach problems in the elderly is the illnesses.
Wrong. Although the incidence of gastric cancer in the elderly group to a higher, but many hospitals in China reported that 35 young people under the age of gastric cancer incidence rate has reached 6% -11%, and a higher degree of malignancy. Due to pressure young people to learn work, rest, eating rules, the incidence of gastric ulcers and other stomach problems is not too low, so if the unknown causes of upper abdominal discomfort, bloating, pain, gastric flu, anorexia, nausea, vomiting, poor appetite, drowsiness, fatigue easily, sexual wasting and anemia, tar-like stool or hematemesis, to the hospital in time.
Two, I gastropathy years old, they can snack on drugs.
Wrong. 80% of patients with early gastric cancer without symptoms, few symptoms of atypical symptoms is more, with a number of vulnerable gastritis, gastric ulcers and other stomach problems confusion. Therefore, do not opinionated and based on past experience symptoms of the disease to determine its own, solve their own medicines, it is unscientific, most likely interfere with the early diagnosis of gastric cancer.
Three, I have been suffering from gastric ulcer for more than half of the stomach, it is no longer possible for gastric cancer.
Wrong. In most of the stomach after resection of it is still possible for gastric cancer, gastric cancer medicine called residual. Patients with residual stomach gastric cancer incidence is healthy people 2-12 times, the treatment of stomach problems and medication than 2-4 times higher. Residual stomach cancer occurred because of the loss of function of Helicobacter pylori (pyloric sphincter has two functions, namely to prevent stomach has not yet digested good food into the duodenum; Two is to prevent the intestinal fluid, bile reflux Canal, the protection of the gastric acid environment), duodenum and the bile can be dissolved trypsin epithelial cells to accelerate cell division; bile, intestinal fluid mainly alkaline, these are easily damaged gastric barrier; nitrite remnant stomach bacteria increased production, making cancer nitroso compounds concentration increases; when gastric resection and anastomosis of stimulation and tension high ligation, is likely to become a carcinogenic factor. Not because of the gastric resection of gastric cancer treated lightly, healthy patients after stomach problems, after five years should be done once a year for gastroscopy, not to biopsy examination.
Gastric cancer screening methods commonly used are:
A fiber endoscopy (commonly known as gastroscopy); 2, X-ray barium meal examination; 3, B-; 4, immunological tests: If CEA; 5, CT.
Early gastric cancer conventional CT difficult, relying mainly on double-contrast barium and fiberoptic endoscopy.
X-ray barium meal examination is the main gastrointestinal cancer screening methods, particularly stomach-low double contrast examination can be as small as 0.5 centimeters that the small gastric cancer or small gastric cancer. Before serving 1-2 day suspension thorough X-ray or affect gastrointestinal function drugs, bismuth follows carbonate, calcium gluconate; Before the 1st Java easily eat less food, dinner after fasting; There gastric retention of patients check the night before gastric lavage; The whole digestive tract barium meal examination on the 2:00 service sulfate barium 100 grams of powder with water temperature 200-300 ml - suits; relaxed mood, as ingestion of barium no harmful effects on the body that will not be absorbed, with the feces excreted, the inspection after 1-2 days of the white stool, but within three months of pregnancy can not do the inspection.
Gastroscopy and biopsy is the gold standard for the diagnosis of gastric cancer, doctors determined no contraindications can be related to the inspection, examination subjects fasted for eight hours before, it is estimated that delayed gastric emptying, fasting need more time, pyloric obstruction, should be re-examination of gastric lavage. Admission postoperative gastric biopsy were not immediately consumed drinks and food rough. Gastroscopy that many patients are reluctant to accept too painful. In fact, under the conditions of modern technology, an endoscopic examination can be completed 10 minutes, some sedatives inspection service can reduce pain, many hospitals now launched a painless gastroscopy.
As early gastric cancer five-year survival rate after surgery is about 80%, so attention should be paid to patients with early gastric cancer follow-up. These diseases include: 1 chronic atrophic gastritis: cancer rate was 8.6% resilient%; ② gastric polyps, especially multiple adenomatous polyps, cancer rates as high as 14% -59%; ③ cancerous ulcer rate of 1% -15% ; ④ remnant stomach; ⑤ gastric dysplasia, moderate and severe dysplasia with early gastric cancer are very close to some very severe hyperplasia as early gastric cancer.
Gastric cancer prevention is very important to the diet, eat fresh fruits and vegetables, eat more of vitamin A, B, E food, appropriately increase protein, dairy, milk intake and to protect the gastric mucosa. Eat less or eat pickles, left. Blah smoked, fried, moldy food, alcoholic drinks and tobacco bogey.
