Decipher is a genetic analysis of the tumor itself. It determines the genetic mutations in the tumor. You want this information without regard to treatment, although it can influence treatment. It will tell you whether his tumor isandrogen active and whether the tumor is aggressive, whether this tumor is likely to metastasize and sometimes tell where it is likely to metastasize to and how good his immune response has been.
The test is done on biopsy material already drawn. So all you have to do is call the doctor and request it.
It can be important to consult more than one Oncology Radiologist.
