Potential side effects of cryosurgery for non-melanoma skin cancer

Side effects can occur with any type of treatment for non-melanoma skin cancer, but not everyone has them or experiences them in the same way. Side effects of cryosurgery will depend mainly on the area of the body treated. The side effects of cryosurgery are often less severe than the side effects of other cancer treatments.

Side effects can happen any time during, immediately after, or a few days or weeks after cryosurgery. Most side effects go away after cryosurgery is completed. Late side effects can occur months or years after cryosurgery. Some side effects may last a long time or be permanent. It is important to report side effects to the healthcare team.


Pain often occurs after cryosurgery due to tissue damage. Check with the doctor if pain does not go away or pain medications do not relieve the pain.
