Gastric cancer prevention and other cancers, the key lies in “early" immediate early discovery, early diagnosis and early treatment. Then, gastric cancer what can not be early aware and take preventive measures it? The answer is yes.
Over the last decade, scientists at home and abroad through long-term observation and study of gastric cancer patients found that starting from a certain part of the stomach tissue cells become cancerous, the clinical signs and symptoms, is a slow process, the normal cells in different the long-term effects of the cancer-causing factors into cancer cells, is a gradual process from quantitative to qualitative. This process, medically known as “pre-cancerous". The period also stage the optimal therapeutic effect.
As the name suggests, the preparatory phase of pre-cancerous gastric cancer cell evolution, which includes the status of pre-cancerous and pre-cancerous damage. The former refers to the clinical prone to malignant systemic or local, state or disease, including chronic atrophic gastritis, chronic gastric ulcer, gastric polyps, gastric remnant; The latter is pathological changes, including proliferative changes and intestinal epithelial metaplasia, moderate and severe dysplasia with intestinal metaplasia. The concept of “pre-cancerous", does not mean that inevitably develop into cancer, but cancerous potential trend a sign of a significant increase in the risk. The majority of precancerous lesions “precipice", the long-simmering, even “repent and be saved" subsided recovery. Only a relatively small part of the continued “obstinate", and ultimately to become cancerous.
Gastric precancerous lesions do not need to worry about, as long as the proper treatment, the whole “Guido fierce less. However, the results of the following gastroscope pathology or X-ray inspection needs to pay sufficient attention to: (1) moderate or severe dysplasia; (2) coliform metaplasia or over the age of 40 is not associated with severe the dysplasia; (3) gastric ulcer lesions larger than 2 cm in diameter, especially in the lesser curvature of the stomach ulcers longer course; (4) adenomatous, sessile or diameter greater than 2 cm, larger stomach polyps; (5) associated with intestinal metaplasia and to especially severe dysplasia atrophic gastritis. For these changes, we need to be closely observed, periodic review, once the lesions suspicious, should be timely surgery.
Gastric cancer has a serious threat to human health, is still in its early often have no obvious or specific symptoms, difficult to arouse people’s attention. When to affect the function of the stomach cancer development and the formation of ulcers or gastric motility and stomach volume change occurred before obvious symptoms. At this point, the diagnosis has also delay the disease have reached late. How to change from their own feelings and symptoms to identify early warning signals of gastric cancer, can be summarized as the following: (1) abdominal pain lose the regularity of the original ulcer disease episodes, significantly different from the usual; (2) stomach problems, eating or after medication to no avail, but heavier; (3) the past stomach upset, loss of appetite, weight and physical without much impact, but now the loss of appetite, fatigue and obvious weight loss; (4) for blood in the stool or vomiting; (5) of unknown cause epigastric discomfort, fatigue, weight loss; (6) after more than five years after the Pythagorean II gastric surgery, indigestion, weight loss, anemia and stomach bleeding and other symptoms. All these are not taken lightly, and refrain from using the grounds of “doing it" casual clothing Weiyao fallen on deaf ears.
