Alcohol may lower the risk of kidney cancer

Filed under:

According to a study from the Karolinkska Institute in Sweden, alcohol consumption may lower the risk of kidney cancer. The researchers found that the odds of developing kidney cell cancer was 40 percent lower among those who consumed 620 g of ethanol per month versus those who did not drink at all.

Drinking more than two glass of red wine per week was associated with a 40 percent reduction in kidney cell cancer risk compared with drinking no red wine and there were similar trends for white wine and strong beer. There was no correlation between kidney cell cancer risk and light beer, medium beer, strong wine or hard liquor.

The researchers write that the reduced risk associated with wine and beer might be due to the phenolics they contain, which possess antioxidant and antimutagenic properties. However, since the risk also seems to be correlated with ethanol intake overall, they speculate that the alcohol itself might also play a role.
