Cryogun used to spray liquid nitrogen. A common method of freezing lesions is by using liquid nitrogen as the cryogen. The liquid nitrogen may be applied to lesions using a variety of methods, such as dipping a cotton or synthetic material tipped applicator in liquid nitrogen and then directly applying the cryogen onto the lesion.

De Quervain successfully used of carbonic snow to treat bladder papillomas and bladder cancers in 1917. Dr. Irving S. Cooper, in 1913, progressed the field of cryotherapy by designing a liquid nitrogen probe capable of achieving temperatures of -196 °C, and utilizing it to treat of Parkinson's disease and previously inoperable cancer.
Treatment: “Your dermatologist may freeze them with liquid nitrogen, apply other topical treatments or lasers, or give you a prescription for a cream to use at home," Dr. Zeichner says. Alamy ...
Soon, the tall cryotherapy tank is filling with a cloud of super-chilled gas: evaporated liquid nitrogen, one of the coldest substances on Earth. “Okay,” the technician says. “Get in.”
Approximately 1–3 treatments may be needed to completely remove a mole. Typically, a local anesthetic is applied to the treated skin area before beginning the mole removal procedure. [30] For surgery, many dermatologic and plastic surgeons first use a freezing solution, usually liquid nitrogen, on a raised mole and then shave it away with a ...
Due to its use in previous studies, the nitrogen mustard called "HN2" became the first cancer chemotherapy drug, chlormethine (also known as mechlorethamine, mustine) to be used. Chlormethine and other mustard gas molecules are still used to this day as an chemotherapy agent albeit they have largely been replaced with more safe chemotherapy ...
