Advice on teenage son’s mole

Hi! I have had melanoma in-situ and so has my sibling.  I have probably had 50+ moles off since ranging from benign to severely atypical (most mild atypica or benign)

My son is 13.5 and has a small/medium mole on his back. It was a tiny light speck in 2014 and now is 4-5mm dark brown but getting darker. It seems to be changing a bit more rapidly than his other moles but not alarmingly so. It's really his only one on his back. I am inclined to remove as it's coming up on puberty and hard to watch, sun will hit (it's on his shoulder blade so also hard to cover with spf)

Is that reckless of me to just remove a seemingly normal mole? Should I just have it punched out and be done or have his derm check it with a dermatoscope and if it's fine under that, then leave it. I am sick of checking it and looking at it… one day it looks normal to me and then under other light it looks dark and I want off. My gut is it's atypical….

Trying to balance my anxiety with being proactive and thinking of the future (Back, hard to see and my history) but I realize it's a slippery slope. He has new tiny blackish one on leg- so maybe I should focus on that lol

Thanks!
