What deodorant do you guys use?

I dont know what deodorant i should buy, so I thoight I´d ask you guys ;) it is very important for me that it doesn't cause cancer. you know these deodorants that have that special mark on them and it says that they are something (some chemical/substance) free. so if any of you know a deodorant like that that smells good and is healthy plus pretty, go ahead and let me know.
thanks
