How many centimeters above which stomach cancer is not considered early stage

Whether gastric cancer is in the early stage usually does not depend solely on the size of the tumor, but requires comprehensive consideration of multiple factors. Generally speaking, the early and late stages of gastric cancer are mainly judged based on the depth of tumor invasion and whether lymph node metastasis occurs, rather than simply distinguished by the diameter of the tumor. Even so, the size of the tumor can reflect the development of the disease to some extent. Usually, early gastric cancer refers to cancer cells that are limited to the mucosal layer or submucosal layer of the gastric wall, regardless of the size of the tumor. When cancer cells invade the muscular layer or deeper layers, or lymph node metastasis has occurred, it is no longer in the early stage.

So how should we understand these medical terms? We can imagine the stomach wall as a multi-layered cake. Early-stage stomach cancer is like just a layer of powdered sugar sprinkled on the surface of the cake, while advanced-stage stomach cancer is like the powdered sugar has penetrated into the cake and even spread to the surrounding areas. In this way, the difference between early and advanced stomach cancer is not just about how much powdered sugar is on the surface of the cake, but how deep the powdered sugar has penetrated.

In addition to the size and depth of invasion of the tumor, lymph node metastasis is also an important indicator for determining the stage of gastric cancer. Lymph node metastasis is like powdered sugar floating from the surface of a cake onto the surrounding tables, which means that cancer cells have begun to spread in the body. Even if the tumor itself is not large, if lymph node metastasis has occurred, it cannot be considered early.

So, how should we deal with gastric cancer? Regular physical examinations and early screening are key, especially for people with a family history or other risk factors. Gastroscopy is an effective means of detecting early gastric cancer. Although the process may be somewhat uncomfortable, it is essential for early detection and treatment. Maintaining a healthy lifestyle, eating a proper diet, avoiding excessive intake of pickled and smoked foods, quitting smoking and limiting alcohol consumption are all effective measures to reduce the risk of gastric cancer.

In daily life, we are often surrounded by all kinds of health information, but what is really important is to master scientific health knowledge and actively manage health. I hope this article can provide you with some useful information to help you better understand the staging and prevention methods of gastric cancer. A healthy life starts with every little detail. May we all have a healthy stomach.
