Gastroscopic examination of 2.0-2.5 cm neoplasm on the side of lesser curvature suggests that it is a gastric space-occupying lesion, which may be gastric polyp, lymphoma, smooth muscle tumor, etc., and may also be gastric cancer. Further pathologic examination is needed to clarify the diagnosis. Part of the tissue can be removed under gastroscopy and pathologic examination can be performed to clarify the nature. If it is gastric polyp, it can be surgically removed. If it is gastric cancer, lymphoma, smooth muscle tumor, etc., according to the nature and stage of the tumor, surgical resection and chemotherapy can be chosen to avoid the spread of cancer cells. Pay attention to light diet and avoid stimulating foods such as hot pot and barbecue. Eat regularly and quantitatively, do not overeat. Avoid ice-cream and other raw and cold foods so as not to aggravate the development of the disease. If new organisms are found in the lesser curvature of the stomach, they should be clearly diagnosed under the guidance of doctors with the combination of symptoms as well as pathological examination, etc., and should not be judged blindly.
