What causes rise in PSA level?

My father is being treated for prostate cancer with hormone injections since February 2013. His highest psa level was 43. It dropped to almost zero at one point, and had risen to 5 in dec 2013. His latest test shows a level of 28 in jan 2014. He has just had a bone scan which we have no results for yet.
