• Nuclear medicine procedure less costly and painless.

• Myelosuppression may occur before chemotherapy.

• Nuclear medicine procedures are safe with no side effects [24].

Theranostics is a combination of two words **Thera**peutics and diag**nostics**. This is an emerging field of medicine where drugs and/or techniques are used in combination for treatment as well as treatment. It's a game changer as it provides diagnosis as well as therapy in single combination. It is economical as well as less time consuming. It uses PET scan to target tumor receptors which are present in tumor cell. If it is found in the cells radioactive drug is used to treat it. There are not much clinical trials found related to use of application of theranostics in prostate cancer by Australian Medicines

The Nuclear Medicine Imaging approach is revolutionized by use theranostics [targeted therapeutic (Rx) + companion diagnostic (DX)] to establish tools for specific molecular targeting. It provides personalized treatment plan for the patient by targeting specific targets. Various department of nuclear science can utilize
