No one knows the exact causes
of stomach cancer. Doctors often cannot explain
why one person develops this disease and another
Research has shown that people with certain
risk factors are more likely than others to
develop stomach cancer. A risk factor is something
that may increase the chance of developing a
Studies have found the following risk
factors for stomach cancer:
* Age: Most people with this
disease are 72 or older.
* Sex: Men are more likely
than women to develop stomach cancer.
* Race: Stomach cancer is
more common in Asian, Pacific Islander, Hispanic,
and African Americans than in non-Hispanic white
* Diet: Studies suggest that
people who eat a diet high in foods that are
smoked, salted, or pickled may be at increased
risk for stomach cancer. On the other hand,
eating fresh fruits and vegetables may protect
against this disease.
* Helicobacter pylori infection:
H. pylori is a type of bacteria that commonly
lives in the stomach. H. pylori infection increases
the risk of stomach inflammation and stomach
ulcers. It also increases the risk of stomach
cancer, but only a small number of infected
people develop stomach cancer. Although infection
increases the risk, cancer is not contagious.
You cannot catch stomach cancer from another
person who has it.
*Smoking: People who smoke
are more likely to develop stomach cancer than
people who do not smoke.
* Certain health problems:
Conditions that cause inflammation or other
problems in the stomach may increase the risk
of stomach cancer:
gastritis (long-term inflammation of the stomach
anemia (a blood disease that affects the stomach)
* Family history: A rare
type of stomach cancer runs in some families.
