Breast cancer is one of the most invasive cancers, with a high mortality rate;
almost all treatment options are invasive, with significant side effects, and not always
curative. Nanomedicine, the application of nanotechnology to medicine, is an interesting
approach to improving the delivery of anticancer drugs, thus increasing their therapeutic
index and specificity, while reducing side effects. This chapter describe the most widely
studied nanoparticulate drug delivery systems, also discussing nanocarriers in clinics and
recent advances in targeted drug delivery approaches for breast cancer treatment.
