2.Genetic Factors
A positive family history of gastric cancer, meaning a first-degree relative (parent, child, or sibling) who has or had the disease, has been associated with a higher risk of the disease (~three-fold). In addition, certain inherited mutations of genes can increase the risk of gastric cancer.
However, interactions between these genes and environmental factors have also been shown to be key contributors to cancer development. Inherited genetic disorders, such as Lynch syndrome, hereditary diffuse gastric cancer, and familial adenomatous polyposis (FAP) can increase the risk of gastric cancer.
