Hi Cheshire Chris,
If I'm reading your historic PSA results correctly, you seem to have a pattern similar to "two steps forward, one step back". You have had some big drops in the earlier results and then a slight increase before it resumes its downward trajectory. The rate of decline has slowed, but overall, it still seems to be downwards (?). But I understand that any rise is unwelcome and a potential worry. The need for regular PSA testing is like a Big Wheel that we can't ever get off.
I hope the latest result is a blip.
