Gastrointestinal mesenchymal stromal tumors are classified by their growth location, diameter and size, and nuclear schizophrenia. 1. Growth location: Gastrointestinal mesenchymal tumor grows in different locations, and its risk is also different. For example, it can grow in the colon, stomach, small intestine and other parts, or in the peritoneum, abdominal cavity, mesentery and other parts, and its risk is not the same. 2.
