Gastric tumors are abnormal growths that develop in the stomach. They can be benign (non-cancerous) or malignant (cancerous). The most common type of gastric tumor is gastric cancer, which can cause symptoms like stomach pain, nausea, and weight loss. Early detection is crucial for effective treatment. These tumors can arise from different types of cells in the stomach lining. Risk factors include Helicobacter pylori infection, smoking, and a family history of stomach cancer. Treatment options may involve surgery, chemotherapy, or radiation therapy, depending on the tumor's type and stage. Regular check-ups can help in early diagnosis.
