Generally, when gastroscopy reports the result of tubular adenoma with low-grade intraepithelial neoplasia, patients should mainly focus on the treatment of gastritis, pay attention to a light and easy-to-digest diet, do not eat spicy and stimulating and greasy diet, and pay attention to eating less and more meals. In addition, patients can apply some drugs that inhibit gastric acid and protect gastric mucosa. After 3-6 months of treatment, patients need to review the gastroscopy to be alert to the development of other lesions that may lead to cancer. Tubular adenoma with low-grade intraepithelial neoplasia is a pathological finding that is still benign by description and has not progressed further to precancerous or cancerous lesions. Low-grade intraepithelial neoplasia may progress further to intermediate or high-grade. If it is a high-grade intraepithelial neoplasia, it is a precancerous lesion, and further development may be severe enough to become cancerous.
