question: Gleason 6 in one of 12 needles.less than 5%.PSA at time of biopsy was 4.6.Went to UTMB in Galveston Tx. where they have 3 Tesla MRI.Doctor found nothing on MRI except very large prostate.Doctor there said my PSA if size were included in calculations would be .1 and a biopsy would not have been done there.He advised me that a Gleason 6 isn t considered cancer in some countries and advised me to watch my psa and to come back for another mri in a year.What are your thoughts?
