I don't mean to diminish the importance of dermatologists. My brother had 3 melanomas on his thigh. He's a cancer survivor thanks to his dermatologist's keen eye.
I only mean a plastic surgeon is trained to make the least noticeable scar when it comes to the face.
No offense! Carry on!
You know, I don't know much about keratosis, but I work for a plastic surgeon, and he is adamant about removing things, pronto! If your doc says a kearatosis could turn cancerous, I would definitely look for a good plastic surgeon (only because it's on the face--insurance will pay for this) and make an appointment.
When a person has squamous cell carcinoma (not TOO urgent) on their face, we try to schedule their procedure within two months of diagnosis. If it's basal cell -- one month. Melanomas are an entirely different urgent matter. So, I would schedule it now to get it off your mind. Why wait? You can ask your internist for a referral. Please don't settle for a dermatologist, since it's near your eye on your face.
About the auto-immune issues, I really don't know. I wish I couls answer more. Are you an MS patient? I've not 'spoken' with you before. If you're new -- Welcome! If you've been around a while, I'm sorry I don't reconize the name -- I'm pretty awful!
Take care and let us know how it's all going.
