Amongst all efforts for improving oncological management outcomes, nanoparticles enhanced radiation for breast cancer patient's treatment is a novel approach that has grown interest for research in the last decade. Multiple preclinical data has been published, from all around the globe; however, clinical evidence is still insufficient for implementing the method in routine practice and in disease specific management. Gold nanoparticles (AuNP), which may be among the most studed materials, account for the majority of available data; however, some new materials have also been used in preclinical settings.

Without any safety data available at the moment to support an active use, dosimetric in vitro and in vivo information seems to be consistent with a very promising and hopeful panorama for clinical applications. This review evaluates existing dosimetric data in breast cancer tissue, and a probable future impact in treatment choices and patient outcomes, as further investigation is required in a clinical setting.
