I found I developed something tiny like this about 20 years ago...I went to the Dermatologist to have it taken off...I figured lazared or whatever they did...He would not do it...He wanted to just leave it alone...About 6 years ago I found out that all my doctor reports with all the doctors I see, has this at the top alert of something to watch out for...The size and shape pictures were there...It is not that big, but it is watched...I never knew it as he didn't scare me...Now I find that this is a good place for a cancer to start...
I would leave it...Not because I am telling you, but why disturb something that may stay dormant...I understand that this is just my opinion, but I am happy I left mine alone...
Good luck...
