Biopsy of 2 pieces of gastric sinus is not necessarily gastric cancer, but may also be inflammation or polyps. Gastric cancer mostly occurs in the gastric sinus. Biopsy at the gastric sinus during gastroscopy suggests that there is a lesion in the gastric sinus, which needs to be clarified by pathologic biopsy. Whether the result of gastroscopy biopsy is cancer, inflammation or polyp, the doctor needs to make a diagnosis according to the pathological result. Gastric cancer pathology results will suggest adenocarcinoma, undifferentiated carcinoma, mucinous adenocarcinoma and so on. Gastritis results suggest inflammatory changes. Gastric polyps suggest polypoid changes. Gastric ulcer and gastric cancer mostly occur in the side of the curvature of the gastric sinus, so the biopsy of gastric sinus is not necessarily gastric cancer, but may also be other benign diseases, so don’t worry too much, and cooperate with your doctor positively for diagnosis and treatment.
