Cone vs. Cryosurgery. A cone biopsy is a diagnostic and therapeutic test that removes a piece of your cervix and it can then be looked at under the microscope to make sure there is no invasion present. Cryosurgery is just freezing the cervix.
Great. With cryosurgery, the affected area is frozen, which destroys the tissue. How deep this goes depends on the length of the freeze, although there is a limit to that due to the warming effect of the circulation. A cone biopsy, now done by loop excision, removes the affected tissue in pieces. It has an advantage in that the margins can be examined by the pathologist.
