FROST Cryoablation Trial

Cryoablation is available to participants in the Freezing Instead of Removal Of Small Tumors (FROST) Trial, a national study of the use of cryoablation in the treatment of early-stage breast cancer. Dr. Holmes designed and serves as chair of this national trial.  

Cryoablation is a groundbreaking new treatment for breast tumor freezing.  Cryoablation has been used for many years on liver, skin, and cervical cancers, as well as, benign tumors within the breast.  However, cryoablation has only recently been adapted to treat breast cancer.
