If I have a tongue biopsy, what do you suggest for the least invasive way to avoid getting a keloid from the biopsy? (Photo)

I noticed a odd bump on my tounge - my dentist says we should biopsy it- I am a keloider (have major ones on my chest and back and had radiation for those to stop them growing) and I also wear a bite splint at night and maybe thought this was a keloid? Is laser excision best for potential keloid or is oral surgeon with stitches? I have also reacted to dissolvable stitches when I once tried to have my chest keloids removed.
