Mole and freckle

Hi Doc,

What is the difference between a mole and freckle? Can a freckle turn into a mole? Or will a mole just develop on its own. Another thing I wanted to know is how moles develop. I read that the sun plays a role on it. So If I'm in the sun all day is there a chance will mole will develop soon right after (few days to month).

Moles have mole cells (melanocytes) in them.  Freckles just have extra pigment.  Sometimes it's hard to tell which is which without doing a biopsy, but if the spot doesn't look suspicious, it doesn't matter--it can be left alone.  Sun can increase the number of moles people have, but they may occur where there was no sun to speak of.  Freckles can appear soon after sun exposure, not moles.  If there's a specific spot you're concerned about, you'll need to see a doctor in person so you'll know for sure and not have to worry.

Best.

Dr. Rockoff

Dr,

Did you see my last email? I was wondering can a freckle turn into a mole? Or a mole will develop from a new spots.

thanks
