Benign gastric space-occupying lesions are more common than malignant ones, because malignant gastric tumors are mostly formed by benign lesions, and a few are metastases of cancers in other parts of the body, while benign space-occupying lesions include gastric tumors as well as gastric polyps, etc. The incidence of malignant gastric tumors is much lower, including malignant diseases such as gastric cancer and gastric sarcoma.
The incidence of malignant gastric tumors is lower, including gastric cancer, gastric sarcoma and other malignant neoplastic diseases, which are related to geographic environment, genetic factors, Helicobacter pylori infection, food or drugs containing nitrosamines and other chemicals, etc. Tumor cells infiltrate the wall of the stomach and even invade the plasma membrane by malignant proliferation, and cancerous tissues are shown as invasive and solid masses in CT, MRI and ultrasound of the abdomen.
The incidence of benign gastric tumors is higher, including benign mucosal epithelial tumors such as adenomas and adenomatous polyps, and benign mesenchymal tumors such as smooth muscle tumors, hemangiomas and neurofibromas.
In addition, benign space-occupying lesions may also be benign bulging diseases, including gastric fundus glandular polyps, hyperplastic polyps, etc. Gastric polyps also have a higher incidence, which are space-occupying protrusions on the surface of the gastric mucosa due to Helicobacter pylori infection, long-term application of proton-pump inhibitors, and prolonged atrophic gastritis.
Patients should consult the doctor in time to make a clear diagnosis and follow the doctor’s instructions for treatment.
