I had prostate surgery in March at the Marsden at the age of 50. Post-op, my PSA was recorded as detectable after six weeks as 0.01. The exercise was repeated six weeks later (i.e. at the three-month checkpoint) and also came back as 0.01. This afternoon, six months in, I had a telephone appointment with the consultant. He said that there had been a slight rise to 0.03. This might be benign prostate cells emitting PSA, or it might be cancer on the prostate bed. Though based on the data, his money was on the former. Not what I wanted to hear (after negative margins were confirmed etc, as most such cases are undetectable after operation) but trying not to worry.
