Hello, yes he had a psa 6 weeks after brachy, it was 4.9 pre brachy and he thought it was 2.9 but he got confused a few days later and said 3.9 but it had gone down. It can go up after brachy due to the trauma to the prostate, but had gone down a bit. Takes at least a year after brachy to settle.
Good luck with your psa test.
