My grandfather was diagnosed with prostate cancer 11 years ago. He went through all the treatments such as radiation. It was pretty aggressive at first but after some time it seemed to be stable. He has been having good PSA levels since then. In my my grandfather had his PSA checked by this urologist and it was 2.0, just last week (Less than 2 months ago) his doctor ordered another PSA test and it was 4.9. So I was wondering what this meant? My grandfather refuses to have any test done or go back to the hospital or doctors appointments.
