A new research confirming previous researches stated that smoking increased the risk of developing stomach and esophageal cancers.

Apart from this about 30 grams of alcohol on a daily basis, which means two to three glasses of wine, develop the risk of getting cancer five times.

The scientists however negated that smoking and drinking could cause esophageal and gastric cardia adenocarcinoma, cancers that are on the rise these days.

"We suggest that further research should focus on other risk factors for esophageal and gastric cancer subtypes, to search for explanations for these increases," concluded lead researcher Jessie Steevens.

After analyzing more than 1, 20, 000 Dutch adults for 16 years, researchers concluded that smoking increased by 60 per cent to 263 per cent the risk of two main forms of stomach cancer, as well as the two forms of oesophageal cancer.

Results said that those who at the study's start said they were smokers had chances of developing all four cancers more than those who had never smoked. Those who were former smokers also were at risk.
