What is cold ironing?

Also known as cryotherapy, or cryoablation, cold cauterization is an effective alternative to more invasive treatment options, as it is a minimally invasive treatment used to freeze and destroy abnormal tissue.

This is done by applying intense cold to the area to be treated, and this cold results from the use of different types of cooling materials, such as: –

  1. Liquid nitrogen (temperature -196 °C), is the most common and effective refrigerant.
  2. Argon gas.
  3. Carbon dioxide snow (-78.8°C).
  4. Dimethyl ether and propane (-57°C).

Cryotherapy may be used to treat tissue externally, such as warts and skin tags, and doctors may also recommend using it internally to kill abnormal tissue, such as سرطان الكبد And the prostate.
