Interesting topic this. Having survived lung cancer now for 3 years I am a little concerned about the Prostrate. I have had many MRI's and PET scans, the latest PET one month ago and MRI 2 months ago. Both were full body and showed no problems in the lower regions with the exception of "slight calcification of the colon", my question is, does prostrate cancer show up on a PET scan?. anyone know?
