I've been told by several doctors that BCCs are no big deal if treated within a reasonable time frame. I'm surprised so many of you have had them cut out when small as over here that doesn't seem to be the procedure.
Over the last 15 years I have had about 20 BCCs sapped with nitrogen and frozen off. My last doc gave me an ointment to use which doesn't make such a big scab. Makes you look a bit like a spotty teenager!
With 2500 hours in a Bell 47, it's no surprise that my left arm needed more sapping than my right.
