Wow, thank you SO much for the quick replies and the moral support!
InTheShop - My dad is still taking the Finasteride. I've read conflicting reports which state that with the drug, you can usually consider the number doubled. But still, his numbers have been around the mid 3's even while taking it. The Dr. wants to look into this asap since the Finasteride should prevent a rise in the numbers. This is what scares me (and Dad).
Pratoman- I believe my Dad has already been DX with the BPH which is the reason for the medication. I've read where some men just have higher "normal" levels of PSA.
I will certainly keep the forum posted with the results. It's such a caring and compassionate place. I've spent quite some time educating myself on here the past several days.
Thanks again!!!
