Cryotherapy can be an effective treatment option for many common concerns including warts or certain types of skin cancer. If you notice symptoms of these issues, you can schedule an appointment with an expert provider at West Sound Dermatology.
What is Cryotherapy?
Cryotherapy, or cryosurgery, is a method of removing skin lesions by freezing them. The procedure involves applying liquid nitrogen to the lesion in order to damage the unwanted cells. This ultimately causes a blister to form before the lesion safely falls away from the surrounding skin. Cryotherapy may be used as an alternative to other dermatological surgeries. It is generally considered safe for all patients and may reduce pain or risks associated with other surgical methods. The treatment typically stings, and patients may feel some discomfort for a brief period after the procedure.
In a cryotherapy treatment, the liquid nitrogen may be applied to the skin using a cotton swab or by spraying it. In some cases, the treatment may also be completed by applying carbon dioxide snow or DMEP to the skin. This is less common.
Uses for Cryotherapy
Cryotherapy can be used for a range of skin lesions or dermatological conditions. This includes:
- Actinic keratoses
- Seborrheic keratoses
- Basal cell carcinoma
- In situ squamous cell carcinoma
While cryotherapy may be beneficial for some types of skin cancer, it is not recommended for melanoma or pigmented lesions which may be melanoma and require further diagnosis.
