Approaches in the chemoprevention of breast cancer

Nanotechnology in bioscience and therapeutics has advanced tremendously in this decade. Many nanoparticle formulations as well as passive and active targeted agents have been developed and proved effective preclinically in proof-of-concept models of different cancers.Many of these formulations use polymer nanoparticles, liposomes, bubkyballs, fullerenes, carbon nanotubes, dendrimers, isotope tags, and PEG compounds. In effect, nanoparticle formulations have become the norm in chemoprevention. In this paper we review nanoformulations of bioactive compounds that have been tested for their potential mechanistic antiproliferative activity in breast cancer. We also discuss the possibility of enhancing the activity of these compounds using different innovative bioconjugation methods.
