Did you opt for a PSA test? It's not one of the default ones the NHS does.
I've been retired for over a decade so my information is probably out of date.
PSA (Prostate Specific Antigen) is a straightforward reliable assay. Highly specific, accurate and precise. It's assayed using high throughput automated analysers.
It used to be less precise at low (normal) levels, but better assays had come along by the time I stopped doing them.
It's an assay that can give slightly raised values in normal men for no apparent reason, leading to further investigations
As an assay it is excellent at monitoring the course of prostate treatment, or the growth of a tumour. This, in the UK, is its main purpose.
The argument against the use of PSA as a screening test was always the cost / benefit ratio.
It used to be a relatively expensive assay, and you'd have to screen an awful lot of men to detect a small number of cancers. You'd also detect a number of men who are 'normal' but with raised PSA levels.
I /think/ there may also have been an argument that PSA will also detect benign tumours that do not need to be treated.
The USanian health care system does like to play Clinical Bingo (get lots of numbers and see if a disease can be found) there may be a reason for that but it e$cape$ me for the moment.
The predecessor to PSA was dirt cheap as regards reagents, fairly good for screening, but could not be automated - hence unsuitable and too costly for the 21st century (and you had to avoid nookie for a few days before)
