Symptoms of extragastric tumors usually usually depend on the size and volume of the tumor. If the size of the tumor is small, the patient may not have obvious symptoms, but may also have symptoms such as epigastric pain, nausea, vomiting, acid reflux, belching, etc. If the size of the tumor is large, it may invade the peripheral nerves, and cause bleeding, hematemesis, anemia and other symptoms. If the tumor is large in size, it will invade the peripheral nerves, and symptoms such as gastric bleeding, blood in stool, anemia, etc. When the tumor presses the common bile duct, jaundice and other symptoms may occur. It is recommended that patients should go to the hospital for imaging examination when they feel unwell, so that treatment can be carried out according to the nature of the tumor, size of the tumor, and physical condition of the individual. Once the diagnosis is confirmed, the patient should consult a doctor in time and standardize the treatment under the guidance of a professional doctor to avoid delaying the condition.
