Gastric neoplasms refer to abnormal growths or tumors that develop in the stomach. These can be benign (non-cancerous) or malignant (cancerous) and can arise from the lining of the stomach (gastric mucosa) or its underlying layers. Gastric neoplasms are typically classified based on their location within the stomach, histological characteristics, and molecular profile. Risk factors for developing gastric neoplasms include infection with Helicobacter pylori, a diet high in salt and smoked foods, obesity, smoking, and a family history of stomach cancer. Treatment options for gastric neoplasms may include surgery, chemotherapy, radiation therapy, targeted therapy, and immunotherapy, depending on the type and stage of the tumor. Early detection and treatment of gastric neoplasms are important for improving patient outcomes and survival rates.
