Re: PSA 4 weeks and 12 weeks post surgery

Tim,

I wouldn't be too concerned about it. PSA has a half-life of 2-3 days and takes a while to be cleared from the blood. If you assume 3 days then an initial PSA level of 10 would lead to a PSA of .02 after 4 weeks. You should focus on the fact that it went to zero.

Re: PSA 4 weeks and 12 weeks post surgery

Its always worth using the search engine, both here and on the main site to find informaiton on issues of interest. For example this subject has been discussed extensively on a number of occasions - see Explanation for nondecrease in PSA despite prostatectomy? for one of the better ones.

As David says, a PSA taken four weeks after surgery will often show a positive result - in fact I don't know why the test is even taken then. Three months used to be the 'standard' and it is only recently that I've seen mention of four or six week tests.

All the best
