Should I be worried about melanoma, though I�m only sixteen years old?

So I have skin moles, I do not tan often, I use suncream, if I indeed go out in the sun for a longer period of time, but my problem is that one of my skin mole is in an irregular shape, though that particular mole is less than 2mm(0.079 inches) in diameter and it doesn�t get much almost none sunlight at all.And I�m also under 18, so should I be worried?
