[en] This article aims to introduce the progress, mechanism, advantage, disadvantage and application of cryoablation technique, as well as the most advanced instruments in the world nowadays, which have been clinically used for the treatment of cancer, and their operating principles and functions. The following are some of the state-of-the-art cryoablation instruments: the ArcticFront balloon catheter for the ablation of pulmonary vein (CryoCath Technologies Inc., Canada), the V-probe(Endocare Inc., U.S.A.), which can generate iceball of five different diameters by adjusting the slip-twisting position, the 1.47 mm diameter probe (Galil-medical Inc., Israel), the Cryo-s (Metrum-cryoflex Inc., Denmark), and cryosurgery-hyperthermia equipment and 'nano frozen' technique (Liu Jing's Study Group). The prospect of cryoablation technique is also discussed in this paper. (authors)

[en] Along with the rapid development of modern medical sciences, cryoablation therapy, which has been regarded as a new minimally-invasive technique, has been widely practiced both at home and abroad, and at the same time is satisfactory effectiveness for the treatment of breast tumors has strongly attracted the medical workers' attention with each passing day. There is hope that this technique may become an important clinical therapeutic means for tumors in the 21th century. This paper aims to make a comprehensive review of the research progress in cryoablation therapy for breast tumor. (authors)
