@seniormed I see the Mohs surgeon this coming Thursday. But I do not want Mohs. Now I've seen and talked to four neighbors and seen the scars they have from their nose moh's surgery. I also can't sit for that long due to degerative disc disease in lumbar spine. There must be other options for a sidewall basal cell in situ and the squamous cell on tip of nose. Plus as I tried to explain to the dermatologist those tiny pink pimple but flat scaley patches come and go. May be four today and only one tomorrow. So to me this means that the whole tip or end of nose has what have been repeatedly treated as actinic keratosis. So then Moh's isn't going to even touch the others you can't see that day. I did read that blue light doesn't penetrate deep enough though to get the root of them so to speak.
