The incidence of cancer in Argentina is not higher than average. They drink "mate" all day long - they start young, too.
So that may give you the answer you need.
I think the cancer thing is associated with burnt food - like consuming coffee grinds. Mate is toasted, but I do not think to the extent of coffee.
Just my two cents!
