What are the main ways for gastric cancer to metastasize? There are three ways

Gastric cancer tumors invade the connection parts from the stomach wall, which is local infiltration, and this is one of the ways of metastasis. Gastric cancer metastasis also includes lymph nodes, and there is also blood supply in the stomach. Since there is blood supply, tumor cells will continue to infiltrate blood vessels, and then metastasize to distant organs. These are basically the ways.

Gastric cancer is caused by the stomach connecting to the esophagus above and the duodenum below. In this case, some blood vessels and lymphatic reflux are involved. Gastric cancer can metastasize, and it also involves several pathways and ways to allow cancer cells in the body to spread to various parts of the body. So let's take this opportunity to look at the main ways in which gastric cancer metastasizes.
1. Local infiltration <br/>Cancer in the stomach is connected to the esophagus above and the duodenum below. It is surrounded by the spleen, transverse colon, and liver. When the tumor invades these places from the stomach wall, it is considered local infiltration, which is one of the ways it spreads.
2. Gastric cancer can metastasize through lymph nodes <br/>The stomach also has some lymph nodes, which involves the issue of reflux. The stomach has lymph nodes, 16 groups of lymph nodes, and the gastric lymph reflux is in these 16 groups of lymph nodes. This is normal gastric lymph reflux, and the metastatic pathway of gastric cancer is also lymph nodes. However, lymph nodes are divided into the first to third stations of metastasis according to the different sites of gastric cancer. That is, when gastric cancer metastasizes to lymph nodes, there is a stage, and the final prognosis of the patient is determined based on the lymph node stage.
3. Metastasis through blood <br/>The stomach also has a blood supply. Since it has a blood supply, tumor cells will infiltrate blood vessels and then metastasize to distant organs of the body. The most common metastasis is the liver, a distant organ, and must be excluded. The lesser curvature of the stomach is adjacent to the edge of the liver. At this time, it is necessary to distinguish between direct infiltration adjacent to the edge of the liver and distant metastasis. This distinction is the characteristic manifestation of imaging, and the common sites of metastasis are the lungs and bones. Metastasis can also occur in other organs of the body. This is hematogenous metastasis, which can also be called distant cancer metastasis. Therefore, it must be paid attention to.
The above is an introduction to the main pathways involved when gastric cancer metastasizes. As gastric cancer cells spread through the blood, gastric cancer metastasis can also appear in the lymph nodes, and cancer cells may also appear in nearby parts of the patient's body. Therefore, when this disease occurs, it must be treated early to prevent its metastasis.
