I would suggest less guessing and more self education on Prostate Cancer .
Read " Dr. Patrick Walsh's 5th Edition " Guide to Surviving Prostate Cancer ."
Dr. Walsh is the world's foremost authority on prostate cancer. He is the Distinguished Professor of Urology at the Brady Institute of the John Hopkins medical institutions in Baltimore , Maryland, USA .
Regarding Prostate Volume ( size ) , T signal , TI- Rads Score and Tumor Size . These are all spelled out on your MRI Report .
I always , after an MRI Receive . A paper copy plus a CD-ROM & Memory Stick .
Always get a 3T MRI NOT the 1.5T machine .
