I am lucky to have a Dermatologist, who knows I take coumadin, and never ask me to go off it. ..Last year, he zapped 3 spots and today, he shaved a mole off my scalp.and zapped a red spot on my cheek.No bleeding from the mole being shaved. ..just a little sting from the Lanocane? shot. I have had 2 basal cell cancers in the past..and had them removed surgery (before my taking coumadin)so, better to catch those questionable moles, ect. early. Both of my basal cell cancers were on my face.One under my nose flap and one close to my eye. ........Bonnie
