Stomach cancer, also known as gastric cancer, can develop in any part of the stomach. In most regions of the world, stomach cancer develops in the main section of the stomach.

Anything that increases your chances of having a disease like cancer is considered a risk factor. The risk factors for various malignancies are varied. Smoking, for example, is one risk factor that can be modified. Others are unchangeable, such as a person’s age or family history.

However, just because you have one or more risk factors does not indicate you will develop the disease. Many people who have one or more risk factors never develop cancer, while others who do develop cancer may have few or no recognised risk factors.

Several risk factors for stomach cancer have been discovered by scientists. Some of these can be managed, while others are beyond our control. Below are 4 bad habits you should avoid in order to reduce the risk of developing stomach cancer.

1. Excessive alcohol use.

The truth is that excessive alcohol consumption raises the risk of gastric cancer. The main mechanism is thought to be related to the primary metabolites, acetaldehydes, which have a local toxic effect that raises the risk of gastric cancer. By irritating the stomach, alcohol can cause gastritis. The lining of your stomach becomes inflamed, producing discomfort and illness. Gastritis can also be a long-term problem.

2. Exposure to harmful chemicals.

Working in certain occupations or with certain substances can increase your risk of stomach cancer. Working in the rubber manufacturing industry, for example.

There has also been some studies associating stomach cancer to asbestos and inorganic lead compounds, but the evidence is limited.

Workplace exposure to these substances is uncommon, and there are rules in place to protect workers.

3. Excessive smoking.

Smoking is linked to an elevated risk of stomach cancer in a dose-dependent manner, regardless of the number of cigarettes smoked or the length of time spent smoking. Stomach cancer, both cardiac and noncardiac, is increased by smoking. Smoking cessation lowers the risk. According to a meta-analysis of 40 research, the risk was elevated by 1.5 to 1.6 times and was higher in men.

4. Being overweight or obese.

If you’re overweight or obese, you’re more likely to get cancer in the upper area of your stomach (the cardia). This is the point where your food pipe meets your stomach (the gastro-oesophageal junction). Doctors classify malignancies of the gastro-oesophageal junction as stomach (cardia) cancers. They are, however, treated differently from other stomach malignancies.

In the United Kingdom, being overweight or obese causes more than 5 out of 100 stomach cancers (more than 5%)
