We're not sending him the right message here - 80% of oral cancer is attributed to tobacco products and we have had a fair amount of "dippers" on the boards here.
But to directly answer your original question sure you can get oral cancer in your 30's and they are finding more and more earlier cases. You can also die from it - 9,000 or so deaths a year. Heather was 28 when she died and she was originally a stage 1 as I recall. The latest forecast I read are 24,000 new cases this year (the number is higher if you include esphogeal).
You are engaging in a high risk behavior.
