Is it standard practise to burn off moles (no pathology) ? why is this done ?

Moles: The standard practice is when a mole appears abnormal it is biopsied and sent for pathology. A seborrheic keratosis usually appears as a brown, black or pale growth on the face, chest, shoulders or back. The growth has a waxy, scaly, slightly elevated appearance and is treated with liquid nitrogen as this type of lesion is benign.

nevi: In most areas a dermatologist will send the majority of pigmented lesions for pathologic review. Some obviously benign pigmented lesions such as a seborrheic keratosis are usually not submitted for path review.

Moles: Only things that are obviously benign should be burned off (a skin tag, for instance). But "moles" are usually pigmented (dark colored) and anything dark colored should be sent to pathology to be absolutely sure what it is. Even if the doctor believes it is benign, you cannot know for certain if you burn it off. burning off might save a few dollars, but that is not a very good reason.
