The findings of a study, conducted by the researchers at the University of Michigan Comprehensive Cancer Center, and published online in the journal Annals of Surgical Oncology, proved the effectiveness of the fast freezing method to eradicate the cancerous cells by verifying that it significantly impacts the way the immune system reacts.

In the clinical trials conducted by the researchers to verify the usefulness of rapid cryoablation in breast cancer patients, the researchers, tested two cryoablation techniques in mice with breast cancer. In the two comparison methods used, some mice were treated with cryoablation and on the others, surgery was performed to remove the breast tumors.

It was concluded that the chances of spread of the cancer was lower in the mice who were treated by freezing breast tumors method, as the technique helped stop the spread of the cancer by providing an immune system response, that hindered the spread and thereby reducing local as well as remote repetition, which is akin to giving a breast cancer vaccine.

"Cryoablation has strong potential as a treatment for breast cancer", said Dr. Michael Sabel, an Associate Professor of Surgery at the University of Michigan Medical School.
