Help! 

I am in my teens and have never had sex. Two days ago I found this small red bump on the edge of my right labia minora, about  1-2 mm in diameter. It feels a little dry, and hurts just a little if I concentrate enough. I think it got a little better but I am not sure.

is this cancer? I am sooooo worried and embarrassed. Should I tell my parents, or will this go away in a few more days?

please help!!!!!
