Moles causing anxiety

I have a tiny little mole on my scalp, I have a few on my scalp that I've noticed recently, but this is a new mole. I'm 15, so I'm not nessecarily worried because it's a new mole, just because it gets a little bigger each day. It's fully symmetrical, no funny borders, totally normal mole. The question I'm wondering is do new moles develop by growing or do they just appear?

 

A doc will know immediately

I'm a bit too afraid to go to the Doctor's though.

Dont be afraid. They will remove the mole completely in about three seconds and then you never have to think about it again. They removed my daughters in mid sentence as the doctor was telling us he wanted to check it. Wallah it was gone. 

That's not too bad then. I don't even think it was growing now, just a trick of the mind. I probably will get them removed when I'm older though.
