Cartilage pushing towards the surface due to thin skin after Mohs. Is surgery my only option? (Photo)

Had Mohs surgery a year ago; after healing well for several months, developed a white-ish bump near tip of my nose. Went back to Mohs surgeon and she thinks its cartilage pushing towards the surface due to thinner skin at surgical site. She's referred me to a plastic surgeon and suggested I might need a flap or skin graft, and possibly taking some cartilage from upper nose to create more cartilage support at nose tip. Yikes. Might there be other options?
