If you're male and live to over 60, you are going to be in this camp regarding the PSA and intervention for Prostate Cancer. Two GPs, a Urologist and an Epidemiologist (none of whom know each other btw) have all said to me "you will die with this not of this" because they can trace the dynamics of my presentation.

Enhanced imaging and blood tests alone didn't do this: their intuition based on progression and behaviour of the system as a whole did.

Treat the person, have a longterm relationship with your health provider.
