I'm recently diagnosed with the above, symptoms are discoloured patches on lower lip, some swelling and tenderness inside lower lip, flaking skin too. It can be pre-cancerous. GP was useless, so my dentist referred me to hospital. Saw consultant at the Oral and Orthodontics dept and am about to have a biopsy. Anyone else had this? From googling it seems it should be referred to Dermatology - I do have a followup appointment for after the biopsy but wondering if anyone has had a similar experience/advice?
