Cryosurgery for non-melanoma skin cancer
Cryosurgery is a procedure that destroys cancer cells by freezing them. It can also be used to treat some precancerous conditions. For non-melanoma skin cancer, cryosurgery may be used to treat:
- precancerous conditions, such as actinic keratosis
- small, superficial, well-defined skin cancers (basal cell carcinomas in particular)
Liquid nitrogen is sprayed on the cancer cells to freeze them. It can be painful when the nitrogen is applied. The area is allowed to thaw and then is frozen again. The freeze-thaw cycle may need to be repeated a few times. Cryosurgery is used to destroy cancer cells while avoiding nearby healthy cells. After treatment, the person may feel an aching or throbbing sensation in the area.
Advocating for cancer patients
Our staff and volunteers meet with elected officials from local, provincial and national governments to persuade them to make the fight against cancer one of their top priorities.
