Take gastric cancer as an example, the prognosis of progressive gastric cancer is relatively poor, but the 5-year survival rate of early gastric cancer, especially early gastric cancer without lymph node metastasis, can reach more than 90% after endoscopic or surgical treatment. Therefore, if you are unfortunate enough to have this disease, don’t panic and go to the hospital to evaluate your condition in time to get the best treatment. In addition, it is now advocated to intervene in precancerous lesions of gastric cancer as well. For example, moderate to severe atypical hyperplasia (also called high-grade neoplasia) of the gastric mucosa also requires timely excision and treatment.
