For external lesions/tumors, liquid nitrogen is applied using cotton swabs or spraying device and for internal tissue growths/tumors, liquid nitrogen is used with the help of a probe. Liquid nitrogen freezes the tissues at cellular level.
In whole body cryotherapy, patients are exposed to temperatures below -100 degree Celsius. Liquid nitrogen and refrigerate cold air is used.
A cryotherapy procedure may take a few minutes to a few hours, depending on the area being treated.
For skin lesions, a cryoprobe may be put through the skin. To reach to tumors inside the body, laparoscopic tube may be used to help to position the cryoprobe.
The procedure may be performed under local anesthesia for external lesions, whereas to reach cancer cells inside the body, general anesthesia may have to be given.
After cryotherapy, the frozen cells thaw. The internal tumor cells are naturally absorbed by the body and the external tumor cells form a scab. Patients recover in a few days. Recovery is not as time consuming as it is with other invasive surgical procedures.
Risk and Complication
Numbness and tingling sensation may be caused in treated areas.
Redness and irritation of the skin may also occur. There may be some pain and discomfort in the treated area.
