​Both current and former cigarette smokers may have high risk of developing stomach cancer.

This study examined how cigarette smoking affects the odds of developing gastric (stomach) cancer. Researchers reviewed a 10-year old data extracted from studies published between 1997 to 2006 that investigated the association between smoking status and stomach cancer risk.

The team of investigators discovered that current and former smokers had higher chances of developing gastric cancer than never smokers. Cigarette smoking was found to increase stomach cancer risk by 43% in former smokers and 57% in current smokers in this study. The findings of this study suggest that cigarette smoking may promote the conversion of healthy cells to cancerous cells and tumors in the stomach.
