Abstract: This paper presents a review of the importance and role of precision medicine and molecular imaging
technologies in cancer diagnosis with therapeutics and diagnostics purposes. Precision medicine is progressively
becoming a hot topic in all disciplines related to biomedical investigation and has the capacity to become the paradigm
for clinical practice. The future of medicine lies in early diagnosis and individually appropriate treatments, a
concept that has been named precision medicine, i.e. delivering the right treatment to the right patient at the right
time. Molecular imaging is quickly being recognized as a tool with the potential to ameliorate every aspect of cancer
treatment. On the other hand, emerging high-throughput technologies such as omics techniques and systems approaches
have generated a paradigm shift for biological systems in advanced life science research. In this review,
we describe the precision medicine, difference between precision medicine and personalized medicine, precision
medicine initiative, systems biology/medicine approaches (such as genomics, radiogenomics, transcriptomics, proteomics,
and metabolomics), P4 medicine, relationship between systems biology/medicine approaches and precision
medicine, and molecular imaging modalities and their utility in cancer treatment and diagnosis. Accordingly,
the precision medicine and molecular imaging will enable us to accelerate and improve cancer management in
future medicine
