Frans, LOL- I had a couple precancerous spots frozen a couple weeks ago-Unfortunately this spot was on the back of my neck and about 7/8ths by 1 1/8 inches. Back where I couldn't see it and didn't think about it until someone asked me about it. I dismssed it as an old scar-Then a few months later I got asked again, looked at it using 2 mirrors and made an appointment with the dermatologist. Like Che said-WEAR SUNSCREENFreeze 'em & flick 'em!
Glad it went o.k.
