Is a mole on the scalp normal?

[Orchid1]

I'm in my late twenties and i've had a raised mole on my scalp for at least the past few years which hasn't really bothered me however I can't help feeling that it's grown ever so slightly bigger recently and whenever you type it into google it of course mentions the big C. Does anyone else have such a thing or should I just get down to the docs pronto?
