Am I at risk of lung cancer?

I am only 20, but I have been working in a dirty warehouse for 2 years now. I work part time, but I use a spray adhesive everyday, which I am afraid might cause long term damage later on. Some of the boxes I move from top shelves have a white dust, which I inhale occasionally. I really like the job, but I think it's time for me to think about my health before the money, and concentrate on my education. Do you guys think these two years I have worked there have already caused damage that will appear later in life, or was my exposure not long enough? I am really scared I have messed up my health, and that lung cancer will show it's ugly head later in life. Any advice??
