I'm not really sure what you are meaning when you say aggressive. Cell morphology is what comes to mind when you say aggressive. The Gleason scores are determined by the lowest and highest degree of differentiation from normal cells. If you look at a biopsy slide and the greater number of aberant cells are scored at a 3, but you also have cells that are morphed to a 4 but not as many, you Gleason score will be 3 +4 or 7. If the majority of cells are 4 but there are fewer that are 3 your score will be 4+3 or 7. These two scores are both 7s, but they are different 7s. So, in my case I have a 3+4 and a 4 + 4 or a 7 and 8. Still you take into consideration how many cores were taken at biopsy and how many contained cancer cells. 10 positive cells out of 12 with Gleason scores of 7 or 8 is different than 2 of 12 cores being positive even if the Gleason is a 7 and an 8 total scores. Now, what about the percentage of cancer cells found in each positive core? A core containing 80% cancer cells is different, as you can imagine, that one with 14%. Lastly, the PSA level should be an indicator of a good or poor prognosis.
Someone please correct me if I'm wrong here, but a Gleason 3 in time will likely be a 4 or 5 as it continues to differentiate if it isn't treated. When someone says aggressive I wonder if some mean advanced or a cancer that has advanced to where it has broken free of the prostate and has metastiasized.
You are a young man, and while you are wise to have annual DRE and PSAs, the only thing you really can or need do is think about your over-all health. Get exercise, eat well, and toss some dehydrated tomotatoes in the mix if you like. Really, I'm not discounting your concerns, but as we baby boomers enter middle and old age, you can bet that research on prostate cancers is going to pick up dramatically and by the time you are diagnosed -IF- you are diagnosed, the treatment considered the gold standard may be one shot or a pill.
Be well and forgive me in errors in the information I gave you - I'm confident, and hopefull, that someone will/would correct any errors.
Wouldn't it be just terrible to be preoccupied with cancer, diagnosis, prognosis, and then walk outside and get hit by a bus? Many things are even more dangerous than cancer.
Be well,

Diagnosis 7/08 PSA 6.8 , DRE negative
Biopsy 7/08 2 or 12 cores positive with 14% tissue involvement Gleason 3+4 (7) and 4+4 (8)
Bone scan negative - MRI evaluation of my prostate and area was negative
8/26/08 had my first Zoladex shot (8 days ago) - I can't tell any difference so far.
No hot flashes and no ED. As I understand it, I'll be on Zoladex for 2 months and then begin IMRT.
My surgical urologist suggested surgery. my Radiology urologist said that either would work just as well.
I chose IMRT because the side effect profile seemed worse - from what I've read - than radiation.
