Why is my PSA Fluctuating?

[Guest guest]

Does anybody have any theories as to why my PSA dances around? My previous

urologist said he didn't know. The latest swing seems profound. I'm in a new

town, and my new urologist is in too much of a hurry to answer questions. I'm

doing watchful waiting/active surveillance. Apart from prostatitis, what might

be the explanation? Here are my numbers.
