The nanotheranostics sector provides a very promising strategy for monitoring drug biodistribution and pathology longitudinal processes by integrating the imaging and drug delivery functions in one single nanoformulation, providing vital insights into the identification of tumour and predicting the efficacy of nanomedicine. For its unique properties, which include their small size and biocompatibility and ability to permeate the cellular membrane with carrying drugs, nanomaterials have been used for various biomedical applications. This book covers the progress made in hormone-related cancer and their management by nonmedicinal therapy for targeting the hormone regulated cancer with their clinical progress and clinical hurdles.
