Waiting for a biopsy for a possible basal cell carcinoma on my nose. Has anyone had this biopsy, and then surgery if diagnosed?

I'm awaiting biopsy for a probable basal cell carcinoma on the nose which could mean surgery.  Has anyone been through this. I'm worried about how this will affect my appearance short or long term as my work is face to face teaching including with children.  Just wondered if anyone else has had treatment for this condition.
