Over 2 years ago I was diagnosed with Prostate Cancer. Gleason of 3 + 3. Have been on active surveillance and have PSA tested every 3 months. My PSA levels range around 5 - 6 with a high 6 months ago at 6.99. My latest PSA came back at less than .1 which is my lowest score ever. Has a miracle happened? What should I make of this?
