Nodule on Prostate

Had a physical 3 months ago with a normal PSA level and nothing noted on prostate.

This morning, had another physical (labs will be back next week) but the PA did find a very small nodule on one side of my prostate. I am being referred to a urologist for further looks, but how concerned should I be at this point? He mentioned it could be many different things and not cancerous, but just concerned that something came up in the last 4 months.
