Does smokeless tobacco cause cancer

Cancer doesn't just come after a certain date. You hear stories of people getting it after just their first dip but then some people never get it after a lifetime, I have been chewing for five years know and I ask the same thing. But it could happen tomorrow, or never. The best thing to do is to not chew in only one spot, switch it around once a week or after it starts to hurt in one area, if you start to see dead skin or white patches STOP RIGHT THEN! No one likes a quitter but sometimes you got to do what you got to do!
