Does stomach cancer run in families?

Yes, it can. The most frequent causes for stomach cancer include alcohol & tobacco use, chronic acid reflux, and exposure to a bacteria called h. Pylori. Much less common are inherited forms of stomach cancer. When present, this type of stomach cancer is often related to a mutation in one of the brca genes, which is more commonly associated with breast cancer.
Rare. It is usually not associated with familial genetics.
