Cryotherapy for Wart Treatment: What You Need to Know

Written by Dave

As we all know, Warts appear on different areas of the body including the hands, feet, arms, legs, face and other body parts.

Warts vary depending on the type and where it can be found. To be able to prevent ourselves from this infection, we should know what causes it and how they can be treated.

One very popular form of therapy involves ‘freezing’ the wart in a process called ‘Cryotherapy’ – but is this the right treatment for you?

Consider the following:

What is Cryotherapy?

Cryotherapy is when a wart is frozen using a cold substance like liquid nitrogen. Tissues are super frozen to destroy wart.  Cryotherapy is done using a cotton swab that has been dipped into liquid nitrogen or a probe that has liquid nitrogen following through it. It is a standard treatment for wart.

What are the Goals of Cryotherapy?

The major goal of Cryotherapy treatment is to destroy wart, stimulate an immune response to fight the virus or both. It aims at destroying the HPV that causes it. Cryotherapy is used if quick treatment is desired and it is used for people who can tolerate moderate short-term pain.

Do I need to go to the Hospital, or can I do it at Home?

Cryotherapy can be done at home, and it can be done in the hospital.

Is there Pain?

Pain from Cryotherapy can last up to 3 days. Healing is quick for like 7 to 14 days, and if the treatment is properly done, no scar will remain. Hours after the treatment, a blister may form and if the blister breaks, avoid it touching another place by quickly cleaning it because the fluid may contain the wart virus.

The blister will dry up after few days, and the wart will eventually fall off. No special care is needed during healing, all you need to do is to wash the affected part gently once or twice in a day to keep it clean. A bandage or dressing is only required if the area rubs around a cloth or if the area can be injured easily.

What Actually Happens?

During Cryotherapy, the wart and the skin around it would have been cleaned, and then a cotton swab, spray or cryoprobe (Long pointed device) will be used to apply the liquid nitrogen to the wart, and it may take up to a minute for the wart to freeze.  Cryosurgery/Cryotherapy works as a result of the destructive power of the cold temperature of the body cells. Water ice crystals form inside cells and as they develop, they push through the cell walls resulting in cell death.

Are there any Risks?

Some of the risks of Cryotherapy wart removal include the following:

  • It may cause the treated skin to be lighter or darker than the skin around it.
  • Blood blister may also form if the freezing of the skin cells causes localized to blood vessels that feed on the wart to rupture.
  • Wart Cryotherapy usually requires more than one treatment to remove a wart completely.
