We are in similar situation.
With a PSA reading of 9.1 in October 23 I had a biopsy in January 24 - nothing found.
PSA in July 24, 5.3 and in Jan 25 up to 7.4.
Shortly before last PSA test my follow up with Consultant was postponed from February 24 to September 24. The NHS app says my recent rise in under review at Urology.
