I have loads of seborrhoeic keratoses all over me. And skin tags. And other sorts of very decorative moles and warts. I must look like a toad.
I was sent to the Dermatology dept at the local hospital to have them all looked at, every inch of me, and fortunately there's no melanoma/squamous/basal among them. The lovely Thai specialist (she wore a sort of traditional silk dress) offered to burn/freeze the larger ones off, but I wasn't bothered.

She did say I should go back every couple of years to have them examined for any changes.
