breast tumor detection using cst

hi all.. i need your guide. how to exactly the right way to detect tumor using cst? do we need to assign the material properties to 1st order debye model? am i correct to say that frequency limits 1-2.5GHz for antenna is used to detect the tumor?

There was a recent thread on this, although the main point of the thread was about power accepted by an antenna.
As someone who did their PhD in medical physics, I think you are wasting your time, but read my response on the other thread.
