The exact reasons that lead to stomach cancer are not known, but researchers argue there are factors that increase the risks of developing it.
These factors include being older, being overweight, struggling with infections that are left untreated, and smoking, among the rest.
According to Cancer Research UK, “Infection with Helicobacter pylori (H. pylori) causes around 40 out of 100 (around 40%) stomach cancers in the UK.”
It is a bacteria that lives in the mucous which lines the stomach and spreads though contaminated food and water. For some people, this bacteria will not cause any issues, but for others it can cause inflammation and stomach ulcers, risk factors of developing stomach cancer.
According to NHS, the early symptoms of stomach cancer are mild and hard to spot, usually because they are also related to other conditions. They include persistent indigestion and heartburn, rapped wind and frequent burping, feeling very full or bloated after meals, and persistent stomach pain.
Symptoms during more advance stages of stomach cancer may include blood in the stool, loss of appetite, and weigh loss.
However, when it comes to stomach cancer, research believe that certain blood types are more prone to this awful disease than others.
Findings of a recent research, those with the blood type A, B or AB could be dramatically more likely to develop some types of deadly cancer, Daily Mail reports.
The study conducted on 50,000 Iranians showed that those with type A, B or AB blood — around half the UK population — have a 55 per cent higher risk of developing stomach cancer, compared to those with the O type.
Other research suggests that those with the AB blood type had a 45 per cent higher chance of developing liver cancer. The same research found that people with O and AB blood types have a lower risk of pancreatic cancer. In the UK, O positive is the most common blood type, while AB negative is the rarest, making up only 1% of the population.
How and why the blood type is related to the risks of developing certain types of cancer is something researchers are yet to determine.
