Studies have shown that even small amounts of alcohol consumption can increase the risk of breast cancer, and a 2011 study published in the Journal of the American Medical Association (JAMA) gives even more detailed data.
- People who drink 5g to 10g of alcohol per day (about the same amount of alcohol as 3-6 glasses of red wine per week) have a 15% increased risk of breast cancer;
- People who drink about 50g of alcohol every day have a much higher risk of breast cancer, 1.5 times higher than non-drinkers;
- A 10g increase in alcohol intake is associated with a 10% increase in breast cancer risk;
- A 10g increase in alcohol intake is associated with a 10% increase in breast cancer risk
- The risk of breast cancer is also increased by occasional one-time excessive drinking without alcohol, and this risk is most pronounced in premenopausal women.
