It is 5 years after the year of original treatment - that takes 1 year to complete and I began treatments in January 2012.
PSA remains 0.12 - 0.17
The fluctuation is normal and has to do with those surviving prostate cells that produce PSA.
Should PSA levels ever reach a 1.5 level, and a subsequent test delivers the same result, then it is a time one needs to return for additional tests.
Over a 1.5 PSA level is cause for concern... if it remains at that level.
