So I had a few of these pop up on my chest and arms a couple years back. They're super common, especially as we get older. My derm told me the same thing - totally benign, nothing to worry about health-wise. If they're bothering you aesthetically, removal is definitely an option. There are a few different methods like laser treatment, electrocautery, or cryotherapy. The laser option seemed to be the most popular from what I researched. Just make sure you go to someone who knows what they're doing because you want minimal scarring.
