This webinar is aimed at breast surgeons across the spectrum experience. This webinar will address how surgeons need to consider a future without Tc99 as an option for sentinel lymph node biopsy, and the effectiveness and reliability of the potential replacements. It will assess the long-term availability of radioactive isotopes, review the proven clinical efficacy of tracers, before analysing the logistical benefits, opportunities for further utilisation, advanced techniques, and additional benefits for patients.
