Alcohol addiction increases risk of related cancers

The high-income countries were Sweden and Canada; upper-middle-income countries were Argentina, Brazil, Chile, Poland, South Africa and Turkey; lower-middle-income countries were China and Colombia; and were India and Zimbabwe.

The research, published in The Lancet journal, included 114,970 adults, of whom 28,813 people (25 percent) were from low-income countries.

Current drinking was associated with a 51 percent increased risk of alcohol-related cancers and a 29 percent increased risk of injury in current drinkers.

Although current drinking was associated with a 24 percent reduced risk of heart attack, there was no reduction in risk of mortality or stroke.

High alcohol intake and heavy episodic drinking were both associated with significant increases in risk of overall mortality.

For higher-income countries, current drinking was associated with a 16 percent reduced risk of combined disease outcome, while for lower-income countries, current drinking was associated with a 38 percent increased risk.

According to lead author Dr Andrew Smyth from the Population Health Research Institute at McMaster University in Canada, "the data support the call to increase global awareness of the importance of harmful use of alcohol and the need to further identify and target the modifiable determinants of harmful alcohol use".
