Patients with gastritis may undergo biopsy when the inflammation is obvious, or when there is mucosal erosion, or when there is a suspicion of gastric cancer. Biopsy can be used to check the severity of the lesion or the nature of the lesion, for example, when there is a suspicion of early gastric cancer or a suspicion of malignant giant ulcer, a biopsy can be taken to rule out the possibility of a tumor, as well as to clarify the benign or malignant nature of the tumor. In addition, gastritis biopsy is not always have a special condition, or suspected of having a tumor, there are times when you can also check for Helicobacter pylori by doing a biopsy in the area of gastritis and gastric sinus. Do not suspect that you have a particular disease after having a gastroscopy to determine gastritis and having a biopsy, but be sure to relax and cooperate with your primary care physician.
