i finished imrt treatment in june of '11. since then my psa has steadily dropped. i've been getting it checked every 4 months. started out at 5.1 just before treatment and now i have had a reading of .2 the last two psa checks. i would imagine that will be my nadir. is there any chance that the psa could increase again?
