@vonny,
Congrats, vonny! I was diagnosed with prostate cancer in 2008, and went through eight weeks of radiation treatment. I relied on what my doctor and the other specialists told me about the best way to treat the cancer, and I also did some research on the internet. My Gleason score was 4/4, so I agreed on the radiation treatment, and I've been well with no recurrence. I get my PSA checked about once-a-year, and it shows lower than 4 (normal).
Since I had faith in my physician and other specialists at Kaiser, I didn't worry all that much.
