During cryoablation, a thin, wand-like needle (cryoprobe) is inserted through your skin and directly into the cancerous tumour. The probe is guided using ultrasound. A gas is pumped into the cryoprobe in order to freeze the tissue. Then the tissue is allowed to thaw. The freezing and thawing process is repeated several times during the same treatment session.
Cryoablation has been successfully used to treat various type of solid tumours, including breast carcinomas, as well as benign breast lumps such as fibroadenomas. This ablation method has the advantage of being a minimally invasive procedure useful in various clinical situations, including early breast cancer and metastatic breast cancer, when co-morbidities preclude the use of surgical treatment.
