I can completely sympathise with how you are feeling at the moment. The waiting and not knowing is the worst thing, but then I suppose the knowing is pretty crap too. Hopefully you just have an enlarged prostate, which is causing your raised PSA.
My husband had a uti, his first PSA was 9.5, thought this was raised due to the infection, but then after the antibiotics his PSA was 7.3. Still too high! We then found ourselves on this path of MRI, then template biopsy, now told we have PCa. Gleason 6, grade 1, but because the MRI showed the tumour up against the prostate capsule, they have staged it at T3a. I'm devastated and worried about my husband. He is due to have the robotic surgery on the 10th Dec. The surgeon said/hoped this procedure would be enough to cure him of cancer. I'm praying it is.
This disease has just snook up on us, no real symptoms, husband is fit and well otherwise.
I know it's so hard not to worry, this is all I've thought about for the past few weeks.
Good luck, thinking of you.
