Coffee and tea consumption were linked to a lower risk of kidney cancer even when the researchers accounted for a number of factors known to affect people's risk of the disease – such as obesity, smoking and high blood pressure.
"Our results suggest that coffee and tea consumption may be associated with a modestly lower risk of (kidney) cancer, whereas intakes of milk, juice and soda were not associated with risk," Lee's team writes.
They say more studies are needed to understand why coffee and tea might be protective against the disease.
