Why is my white spot not removing after doing electrocautery treatment? It's more than 20 days till now, no improvement

Mole removal begins with a comprehensive examination and consultation to determine the likelihood of a mole being worrisome. 
Excisional and incisional biopsies are reserved for suspicious moles.
But its good news that most moles are not problematic and are only
cosmetic, thus leading to the option of scarless or non-surgical mole
removal with lasers and RF and plasma. 
Our office specializes in non-surgical mole removal.

Thank you for your question. Unfortunately, an in-person evaluation needs to be performed to assess your skin and to determine the type of white spot you have. Some white discoloration may or may not be treated with electrocautery. I highly recommend you consult with the practitioner who performed the procedure regarding your questions and concerns. Take care and good luck.
