Cryoablation is the technique of using extreme cold to destroy tissue. It has been used for years in medical applications like dermatology, kidney, prostate, and liver to treat both cancerous and non-cancerous tumors.  Dr. Fukuma at Kameda Medical Hospital developed the technology to remove breast cancer by non-surgical cryoablation.  By this non-surgical treatment, Dr. Fukuma's patients avoid the risks and potential cosmetic impact of major breast cancer surgery.
