A lot of GPs tend to have a pretty casual outlook on spiking PSA results. Mine listened to me when mine went from .8 to 3.1 in a year. I asked for an urology referral and got one right away. The urologist asked about family history which included a brother and father with prostate cancer. He moved me right into a biopsy which confirmed a stage 2 diagnosis.
If it’s only 7 or 8 weeks between PSA tests you should be fine. The speed with which you got things going is to be commended. Good luck.
