In a scene from The Blacklist, one of the characters uses a lighter on a wound to “cauterize” it. It looks painful but works. What exactly is it and is it actually done in medical scenarios?

Yes, it is done in some acute scenarios (example: during surgeries, sometimes removal of tissue like moles or skin tags). As others have said, it’s to close off parts of tissue or remove tissue so they don’t bleed out or lose fluids.
