Recently diagnosed without NHS. PSA result only 2.9.

Hello Everyone, I have been having NHS treatment for another cancer, apparently successfully so far.  Recently I had a PET/CT done privately as this was not offered to me on the NHS and these scans have shown I have prostate cancer.   I have had a PSA test on the NHS and the result has just come back at 2.9.  I am concerned that this will not have been flagged up to my GP as bei)ng outside the normal range and am worried about my referral path to a urinary oncologist.

Is there an obvious pathway for me to get referred for prostate cancer treatment?

(I have been taking Tamsulosin 400ug once daily for over ten years.
