Liquid Nitrogen
Liquid nitrogen, also referred to as cryotherapy or cryosurgery, is a commonly used tool to remove both benign and precancerous skin growths.
How is liquid nitrogen treatment performed?
The liquid nitrogen is contained within a small canister containing a metal tip. With the press of a lever, the liquid nitrogen, which is –196°C, is lightly sprayed into the target area only. The sensation is of a very cold spray; so cold that many patients state it “burns”. The treated area turns red, swollen, darker, and crusty. Occasionally, the lesion could slightly blister. The target lesion will typically crust off after 7-14 days.
What types of lesions is liquid nitrogen used for?
Liquid nitrogen, aka cryosurgery, is commonly used to treat:
Molluscum
Actinic keratoses (precancerous lesions)
Benign growths, especially seborrheic keratoses
Solar lentigos
Certain superficial skin cancers
