Sean & Amin,
There is a lot to learn, but here’s some basics from the data you provided.
The biopsy has confirmed that presence of prostate cancer, and has assigned a “Gleason score” of 3+4=7. High-level viewpoint, Gleason score of 7 is moderately aggressive, but as you may learn later if you dive into more details, 3+4 more favorable than 4+3…too much detail for now.
Almost all patients today present with a Gleason score of 6 or 7. With the information you provided, this cancer is likely to be very treatable through one or more alternative methods.
Amin’s father’s urologist has probably started explaining the alternatives to him, because ultimately he will need to make some sort of decision on what to do. While most prostate cancers tend to be slow growing, this should not be ignored for long.
There is lots of reading material available online. The Prostate Cancer Research Institute has a website is a great starting point. Here’s the link to the “Newly Diagnosed” section: http://www.prostate-cancer.org/pcricms/node/19
Hope that this reply helps you down the path…
