Sequelae of cryotherapy in breast tissue.

Cryotherapy is a novel treatment for benign and malignant breast lesions that is under evaluation. We assessed the acute and subacute outcomes of breast cryotherapy in normal goat teats using physical, microscopic, and imaging modalities. Eight goats were subjected to two freeze-thaw cycles of breast tissue producing a 2cm iceball and sacrificed either 2 or 7 weeks later.
