Why do people have moles on their bodies

What are the chances of a facial mole being removed by the shaving method? My mole is dark brown, slightly smaller than a pencil eraser and a little raised

Okay so i have alot of moles on my face. And sometimes i can tell when they’re about to appear.. like they start out as freckles and then they get darker and darker. I have some freckles on my face now and im wondering if theres anyway to prevent them getting darker? Like a lot of the times i’ve seen them turn to moles and its taking over my face!

I’ve been swimming for about 4 months now (swim team).. outdoors. but i wear sunblock most of the time. i’m asian, and rarely burn. (only tan, and get darker and darker..) i now have tiny black spots on my arm -7 on my right arm, and 5 on my left.. i’m "pretty sure" most wern’t there before (two of the black dots were always there). do i have melanoma or just more moles?

I just noticed this change after childbirth.
