Cancer has remained a formidable challenge in medicine and has claimed an enormous number of lives worldwide.
Theranostics, combining diagnostic methods with personalized therapeutic approaches, shows huge potential to advance the battle against
cancer. This review aims to provide an overview of
theranostics in oncology: exploring its history, current advances, challenges, and prospects. We present the fundamental evolution of
theranostics from radiotherapeutics, cellular
therapeutics, and nanotherapeutics, showcasing critical milestones in the last decade. From the early concept of targeted drug delivery to the emergence of
personalized medicine,
theranostics has benefited from advances in imaging technologies, molecular biology, and nanomedicine. Furthermore, we emphasize pertinent illustrations showcasing that revolutionary strategies in
cancer management enhance diagnostic accuracy and provide targeted
therapies customized for individual patients, thereby facilitating the implementation of
personalized medicine. Finally, we describe future perspectives on current challenges, emerging topics, and advances in the field.
