How is a chalazion diagnosed?

Your healthcare provider will ask you when you first noticed the lump. Your provider will also ask you about your symptoms and check your eyelid carefully. You may need a biopsy if you have chalazions that keep coming back. During the biopsy, your provider will use a needle to remove a small piece of your chalazion. The piece of chalazion is then sent to a lab for tests.
