Causes and prevention of stomach cancer
The stomach cancer is the third most common tumor and the second leading cause of cancer -related death worldwide. However, in developed countries, contrary to what happens with colon cancer, their frequency has decreased. This seems due to improved living conditions, food conservation, and increased consumption of fruits, vegetables and vitamins.
In any case, stomach cancer is a major problem that should be all means to prevent, diagnose it early and treat it in the most appropriate manner.
There are some pre- conditions associated with an increased risk of stomach cancer such as chronic atrophic gastritis gastric surgery (when removed part of stomach ), have a first-degree relative who has suffered or infection Helicobacter pylori.
So, people with first-degree relatives (parents, siblings or children ) suffering from gastric cancer have two to three times more risk of this tumor. In all the above cases ( when present ) is recommended to look for Helicobacter pylori infection and treat. Thus the risk of developing this type of cancer is decreased.
Only in selected cases and in populations with high frequency of gastric cancer (as in Japan) it is advisable to perform periodic endoscopies for early detection of the tumor.
