Stomach cancer, also known as gastric cancer, is a build-up of abnormal cells that form a mass in part of the stomach.
According to the World Health Organization (WHO), 723 000 cancer-related deaths are caused by stomach cancer each year worldwide. It is the fifth most common cancer worldwide, but the third leading cause of cancer-related deaths.
The highest stomach cancer rates in 2018 were seen in South Korea, Mongolia, Japan, and China. But the incidence is increasing in South East Asia, including Malaysia and Indonesia.
Researchers have identified the bacterial strain that may contribute to the development of stomach cancer.
One risk factor for stomach cancer is infection with a type of bacteria called Helicobacter pylori, but the specifics of its impact on the development of tumours have been unclear.
Now, however, scientists have pinpointed which specific H. pylori strain may be responsible for increased stomach cancer risk.
The new researchers' findings may change how specialists screen for and treat this type of cancer.
“H. pylori is a very common infection: At least half the people in the world get it at some point, usually in childhood. We, doctors, aren't sure why it affects some people differently than others”, said Dr Yeap Chee Loong, Consultant Surgeon at the Gleneagles Kuala Lumpur.
“H. pylori can inflame the lining of your stomach. That's why you may feel stomach pain or get nauseous. If it's not treated, it can sometimes cause painful ulcers and open sores in your stomach lining that bleed.
Studies show that people who are infected with H. pylori are also up to 8 times more likely to get a certain kind of stomach, or gastric, cancer.
But this bacterium is only one possible cause of stomach cancer. Smoking, a diet low in fruits and veggies, and a history of stomach surgeries can raise your risk”, Dr. Yeap added.
It is advisable to see your doctor right away if you notice the following in yourself. They could be signs of an ulcer:
If your doctor thinks you may have an H. pylori infection, some tests can tell you for sure:
If you’re worried that you might have an H. pylori infection, do speak to your doctor. It is not difficult to treat the Helicobacter pylori infection once identified. A course of antibiotics will be given to you for at least 2 weeks.
About a month after you finish your antibiotics, your doctor can test for H. pylori to make sure it's gone. If there are still signs of the infection, you may need more antibiotics.
“By successfully eradicating the infection, it can minimize the risk of stomach cancer as much as possible”, stressed Dr Yeap.
