Undecided Question

Moles /beauty marks a good thing or bad thing?

I donno but I get freaked out occasionally over my looks. I have a mole in the MIDDLE of my right cheek so if it does start growing I'll probs be really afraid. Its big already like the size of the flat part on a normal sized screw maybe smaller and its like black. not big on the three dimensional part. I mean its not flat it does raise above my skin and you can tell but it's not that noticeable hopefully. How do iknow if it's growing? It's a part of me and I really don't wanna get rid of it but I don't want it to grow either. What do you think of facial moles? Your opinions on them? And if they're like black?
No hair noticeable. Pleaseee and thankyou,, x
