Abnormal blood lipid levels can induce cancer cells to produce more cancer-promoting oxidized choles-terol,thus increasing the risk of gastric cancer.Lipoproteins are involved in the packaging,storage,transportation and me-tabolism of cells,and studies have found that their metabolism disorders may also be related to the risk of gastric cancer.This article reviews the research progress of serum lipid and lipoprotein levels and gastric cancer,in order to provide new ideas for the accurate treatment of gastric cancer,and provide a new direction for the study of the correlation between gas-tric cancer and lipid and lipoprotein.
