We have talked before about the effects alcohol has on health – ranging from studies showing protective effects against dementia and Alzheimer’s disease,[1] to increasing risk of structural brain changes and cognitive decline.[2] While there have been studies looking at association between alcohol and cancer rates,[3] the general public do not think of cancer when asked to list health risks of drinking (only 13% of adults surveyed were aware of the putative association between alcohol and cancer).[4] A recent paper in the BMC Public Health calculated the lifetime risk of developing alcohol-related cancers and equated this to the risk from smoking.[5]
The authors found that drinking one bottle of wine per week was associated with an increase in the absolute risk of developing cancer during a lifetime of 1.0% in non-smoking men, and 1.4% in non-smoking women. The gender difference was predominantly driven by an increased risk of developing breast cancer. They calculated that this was “equivalent” to a weekly smoking habit of five (for men) or ten (for women) cigarettes.
Although moderate alcohol intake is not equivalent to smoking, there is an argument to increase the level of public health awareness on the risk of cancer from drinking, especially among women. Using cigarettes as an equivalent may help communicate the message of risk more effectively.
