Hi Mick
I can imagine your worry but i think you have to realise that a PSA that low can be regarded as normal. I’d expect them only to consider recurrence if you had a few results showing an upwards trajectory and then they would probably order a scan .At such a low PSA there would be nothing to see I imagine, the guys who had PET scans may say differently I know. John has had many upwards results before changes in treatments and new scans and that has always been based on new pain or symptoms like retention etc. I honestly suspect that’s why you aren't getting what you want. Oncologists generally act on three or more PSA upward changes and take into account the rate of change (the doubling time) as this is indicative of trouble afoot. One thing I have learnt in our long journey with this disease is to have treatment at the right time, not too early and not too late. My husband has survived more than eight years using this as a basis, having only had chemo last year and now finally on Enzalutimide (and doing ok). In all these years his PSA has risen slowly, quickly, slowly, quickly, depending on some mysterious thing I cannot define. He is a Gleason 10 with spread on diagnosis. He has only had treatment when he had symptoms rather than PSA rises alone. I would like to think your oncologist could have explained his thinking much better than I can, but i suspect its a long these lines.
Have you got a specialist nurse you can speak to?
