Stomach Cancer Prevention

On this page I will give you some stomach cancer prevention ideas for you, your family and friends. As in any malignancy, there is likely going to be a multitude of factors that bring about the disease in any one person.

Some of these factors you are likely to know, but some might not seem quite so obvious to you.

Also, in some cases, you can’t actually change your risk of developing the disease, but at least knowing about it will give you greater awareness.

Stomach Cancer Prevention and Risk Factors


Smoking is probably one of the more obvious factors.

As in all tumors, smoking increases your chances of developing the disease, but by how much? Well, the answer is twice as much compared with non-smokers.

It also increases with the number of cigarettes you smoke too and this remains for 14 years after you stop too, so the sooner you stop the better (1).

Stopping smoking is the biggest prevention you can do.

Family History

We don’t choose our families, but if we did maybe we wouldn't chose one with a high probability of gastric malignancy.

The CDH1 gene mutation increases your risk of and can be seen in some families. The condition is referred to as Hereditary Diffuse Gastric Cancer.

Certain medical disorders run in families and are associated with an increased chance of malignancy. These include Lynch syndrome (colon), FAP (colon), Li Fraumeni syndrome and Pernicious Anemia.

Blood Group

If you have blood group is A, you are approximately 1 ½ times the risk in comparison to other blood groups (2).


Diet does appear to have a role. There is evidence that taking high doses of antioxidants such as vitamin A, C and E, in those at high risk, may help to reduce the chances of developing the disease (3).

Smoked, pickled and salted foods as well as diets high in refined carbohydrates are associated with developing tumors.

Conversely, diets high in fiber, fruit and vegetables appears to have a protective role(4).

Being obese is associated with an increased risk (5), so reducing your weight may be beneficial in stomach cancer prevention.

H.Pylori Infection

H.pylori (Helicobacter pylori) is a bacterium that infects the stomach. Chronic carriage of this infection, in your stomach, causes gastritis (a form of inflammation of the stomach lining) which is associated with cancer.

Treating the infection might reduce this, although further research is required.

Targeting people with a high probability of developing gastric tumors may help reduce development of the disease and aid gastric malignancy prevention (6).

Occupational Exposure

There are a number of occupational exposures that have been associated with increased gastric malignancy statistics (7). 

Asbestos exposure is associated with the condition.

Lead is associated with increased probability and occupational exposure occurs in smelters, glass and battery workers.

Exposure to chemicals in the rubber industry.

Dust from wood and coal.

Making sure that protective ware and minimising exposure may help stomach cancer prevention.


Where we live can influence your risk with Japan, China, Korea, Columbia, Ukraine and Russia having high rates of the disease (8).
