A Finnish study found that heavy regular alcohol consumption and binge drinking during midlife were significantly associated with an increased risk of prostate cancer risk. Men who were heavy drinkers (>14 drinks/week) were at a 46% higher risk of prostate cancer compared to those who were light drinkers (≤ 3 drinks/week).
Among current drinkers, binge drinkers – defined as consuming 5 or more drinks in one sitting at least once per month – were at a 28% increased risk of prostate cancer compared to non-binge drinkers. Abstinence was associated with an increased risk of prostate cancer-specific mortality compared to light alcohol consumption.
