Current evidence on brachytherapy as the sole method of adjuvant radiotherapy for breast cancer after local excision (referred to hereafter as 'brachytherapy') raises no major safety concerns. Current evidence on its efficacy is limited in quantity and there is little information on long-term outcomes (5 years or more). Therefore, this procedure should be used only in the context of research, which should address control of local disease with a minimum of 5 years of follow-up. NICE may review the procedure on publication of further evidence.
