My father is diagnosed with Pigmented basal cell carcinoma on the lower eyelid of the left eye. I have googled about various types of treatments regarding it. He has diabetes but at lower stage.Kindly suggest me best treatment procedure where the recovery will be better with minimal damage to the part, chances of recurrence is less etc and where should we perform the surgery (Hospitals suggestions). I have heard about "Moh surgery" and It has less recurrence chances but, it was mentioned that the surgery needs a very skilled practitioner to perform the surgery and a good "Moh surgery" dedicated laboratory. Kindly walk me through the process and suggest me your valuable opinion.
