Stomach cancer is definitely not curable without surgery or some anti-tumor treatment. Stomach cancer is not a self-limiting disease and requires active treatment before it can be cured. The preferred treatment for stomach cancer is surgical resection, which should be as radical as possible, and only after radical resection will there be no obvious cancer cells left in the body, so that it can have a chance to be cured. Because in the process of growth, stomach cancer cells will continue to metastasize and spread along the lymphatic circulation and blood circulation, so if stomach cancer is clinically diagnosed, it should be actively treated, such as active surgery or active chemotherapy and other anti-tumor treatments. If not treated, stomach cancer cells will continue to grow and continue to metastasize, so the best time for treatment may be missed.
