Thanks for the encouragement, Marycain. I will ask the doctor if the biopsy will affect her recommended treatment. Or, if there is an alternative diagnostic option that can be done. I'll base my decision on the lip biopsy on her answers. It's good to 'talk' this through. The visits to doctors can be short and overwhelming. I try to go very prepared and have my questions written down. But that doesn't help when the doctor throws lots of new info at me. Sometimes I don't think of questions until I've left the clinic.
