Radiopharmaceuticals are safe radioactive drugs that can be used as diagnostic or therapeutic tools.
Patients are given a very small amount of safe radioactive medication injected into the blood stream.
The agent specifically binds to and delivers a radioactive payload to tumour cells
The payload can serve either diagnostically (through imaging) or therapeutically or both
In the case of therapeutic applications it allows the mechanism to be extremely selective to precisely deliver a radioactive payload to the tumour
