Everything You Need to Know About Cryosurgery Procedure

Cryosurgery procedure is a type of surgery that involves the use of extreme cold to destroy abnormal tissues, such as tumors.

The surgery most often involves the use of liquid nitrogen, although carbon dioxide and argon may also be used. When liquid nitrogen has a temperature between -346 and -320°F, it instantly freezes nearly anything that’s in contact with it. In the case of human tissue, it can kill and destroy cells upon contact. This is important when the cells you want to kill are cancerous.

Cryosurgery is typically used for tumors or precancerous lesions found on your skin. However, some tumors inside the body can be treated this way as well.

Cryosurgery, also called cryotherapy, is similar to the technique used when doctors freeze off warts using liquid nitrogen spray.

Why cryosurgery is performed

Cryosurgery is used to destroy problem tissues in the body. In most cases of cancer, it’s not the first line of defense.

Cryosurgery is most often performed to treat cancers or precancerous lesions on the skin. It’s also used on some internal organs, such as the liver, when disease and other problems make conventional surgery difficult or risky.

Cryosurgery is used as the primary treatment for early prostate cancer that’s contained in the prostate. It’s also performed when cancer returns after other therapies have been used.

Cryosurgery risks

Cryosurgery does have risks, but they’re considered lower than other cancer treatments, such as surgery and radiation.

The risks associated with cryosurgery include:

  • blisters
  • damage to nearby healthy tissue or vessels
  • infection
  • a loss of sensation if nerves are affected
  • pain
  • scarring
  • ulcers
  • skin discoloration

How to prepare for a cryosurgery

Your preparation for cryosurgery depends on the type being performed. Cryosurgery for skin cancer, which is the main reason cryosurgery is used, requires little preparation on your part.
