elderly gastric cancer

Gastric cancer in the elderly is one of the associated diseases and is a malignant tumor originating from the epithelium, namely gastric adenocarcinoma. The occurrence of gastric cancer is related to multiple factors, with dietary factors being a focus of research. Some surveys indicate that high-salt, highly spiced foods, polycyclic aromatic hydrocarbon compounds produced during cooking, nitroso compounds, mycotoxins, certain grains, and food additives have carcinogenic effects. Gastric cancer ranks first among various malignant tumors in China, and its incidence shows obvious regional differences. In the northwest and eastern coastal areas of China, the incidence of gastric cancer is significantly higher than in the southern regions. The peak age of onset is over 50 years, with a male-to-female ratio of 2:1. The prognosis of gastric cancer is related to the pathological stage, location, histological type, biological behavior, and treatment measures.
