What is Cryosurgery?
Cryosurgery, or cryotherapy, is used to treat external tumors or any abnormal or cancerous tissue with liquid nitrogen. Liquid nitrogen creates extremely cold conditions, which destroy early stage skin cancer moles and lesions, as well as precancerous skin growths called actinic keratosis. San Antonio dermatologist, Dr. Garcia, can effectively use cryosurgery to treat squamous cell carcinoma and basal cell cancers. In this procedure, Dr. Garcia will spray or use a cotton swab to apply the liquid nitrogen to the growth to freeze it away. Cryosurgery is tolerated well by most patients.
What to Expect with Cryosurgery
Cryosurgery is a simple procedure that takes a minimal amount of time. Patients can expect their procedure to be over quickly, however, this is dependent upon the severity of their condition. During the procedure, a dermatologist will sterilize the area being treated. A numbing agent may be applied to the treatment area to help prevent pain and discomfort. Using a cotton swab or spray, the liquid nitrogen is administered, immediately killing all cells that it is in contact with, which is the lesion in question. For this treatment, liquid nitrogen is placed at a temperature between -346 and -320 degrees Fahrenheit. At this temperature, liquid nitrogen instantly freezes and destroys all cells upon contact. The dermatologist will ensure that only the targeted area will be affected by the treatment. Following the procedure, patients may return to their regular routines.

"Sonterra Dermatology is AMAZING!! I have been to several dermatologists in San Antonio and this one is by far the best. Each time I have been in the office the staff have been friendly, professional, and wait times were extremely minimal. I have been working with Daniella Arellano, PA and she is just terrific. She is extremely knowledgeable, explains everything, provides compassionate care and never makes you feel rushed. I know due to COVID there were some issues with scheduling and getting through on the phone, but I booked online without issue. Previously, I had no issue with the office and getting scheduled quickly. Highly recommend this practice, especially Ms. Arellano!"- J.E. / Yelp / May 13, 2020
