 Two major histologic types of gastric cancer are diffuse and
intestinal types. The intestinal type is more frequent in males
and at older ages while the diffuse type shows no difference
between sexes and is more frequent at younger ages. Correa et al
note that the intestinal type is predominant in high-risk areas.
It is also argued that the intestinal type is more influenced by
environmental factors. However, several studies have failed to
find no difference in risk factors between diffuse and
intestinal types.
