The art of cryosurgery.
Cryosurgery is an art as well as a science. Of course just as a sculptor or painter must learn about stone, wood, canvas, paper, chisels, rasps, paint brushes, and other materials, the cryosurgeon must understand the science underlying cryosurgery. He or she must learn the properties of the various cryogens, the apparatus for applying them, the three-dimensional extent of the lesions to be treated, and the tissue content of these lesions. He or she should also know the susceptibility of various portions of the target lesion and surrounding tissues to varying insults with cold.
