Cryotherapy is a commonly used treatment for pre-cancerous lesions, including actinic keratosis (AK), which are often caused by prolonged sun exposure. Cryotherapy involves applying extreme cold, usually liquid nitrogen, to the affected area to destroy abnormal cells before they have a chance to develop into skin cancer.

How Cryotherapy Works: During the procedure, liquid nitrogen is applied to the pre-cancerous lesion, freezing and destroying the abnormal cells. This treatment causes the lesion to blister and eventually peel off as the skin heals. Over time, healthy skin replaces the treated area.

Benefits of Cryotherapy:

  • Non-invasive: Cryotherapy is a minimally invasive procedure that can be performed quickly in an office setting.
  • Quick Recovery: Most patients experience minimal downtime, with the treated area healing in a few days to a few weeks.
  • Effective Treatment: Cryotherapy is highly effective in treating pre-cancerous lesions, with a low recurrence rate when followed by proper care.

What to Expect After Treatment: After the procedure, the treated area may blister, scab, or crust over. This is a normal part of the healing process. As the skin heals, you may see a small white or light-colored mark where the lesion was treated. It is essential to avoid picking at the area to prevent scarring and promote proper healing.

Is Cryotherapy Right for You? Cryotherapy is often recommended for treating pre-cancerous lesions in patients with conditions like actinic keratosis. However, your dermatologist will assess the size, location, and type of lesion to determine if cryotherapy is the best option for your treatment.
