I saw my oncologist last week and had a blood draw. My PSA has risen steadily from immeasurable in January of 2015 (right after I decided to forgo further hormone deprivation) to now a 1.32. While urologists don't get concerned until it hits the 4.0+ range for "normal" males, for those who have been diagnosed with Stage IV, metastatic (lungs), Gleason 8, aggressive PC, the line trailing up quite likely means growth in my unwelcome friend. I'll have a MRI in the next 10 days to get a good look at what's going on there. I the mean time, CBD order is in the works and I should begin that treatment around the same time as the MRI.
This should make for an interesting comparison!
