hard bumps located in my mouth

I have these bumps in my mouth for a couple of days and they are not very painful but they are very very hard and there are two right next to eachother. I am worried about mouth cancer but i don't know if this is possible, i don't know what to think. They are located on the left side of my mouth, on the lip, right where the teeth meet the gums. If you could tell me what it might be that would be great, thanks. I am not a smoker but i have had a couple of cigars and tried chew ONE time.
