Aspects which might influence your treatment options and choice:
GLEASON SCORE or grade is usually a number between 6 and 9 which indicates how agressive the cancer is: with recent screening, most men are now diagnosed with low risk Gleason 6 cancers which is the best score, while grade 8 & 9 indicates agressive high risk PC.
PRINT OUT OF REPORT will also provide other important details like the volume of cancer. Your volume is low with only one positive core. Theis is also indicated by the % of cancer found in each positive core.
Biopsy readings are subjective, so it can be worth obtaining a 2nd reading of the slides and for any future biopsy, as your decisions are being based largely on the reading.
SIZE OF PROSTATE is worth knowing. Different things in addition to PC can effect PSA readings, including infection/inflamation and prostate size which could be influencing the numbers. Sometimes there's an unexplained number: a further PSA test will confirm a trend with the recent jump.
Putting all this together will determine your treatment options and how agressive your treatment should be, but in any event you should take some time to fully consider your options.
Choice of doctor is the most important aspect, regardless of which treatment you choose.
Many urologists will not necessarily present you with an objective outline of your alternatives. Most surgeons prefer surgery, with is often not the only alternative.
You could also obtain the opinion of a medical oncologist who is expert in PC.who can provide an objective view and help in the decision making. Often there are several treatment choices which can be equally effective.
It's difficult to logically compare the prognosis figures for various treatments, because equipment and techniques have improved considerably and top doctors will provide better results than indicated in the average figures often quoted.
There's plenty of information on treatment choices online and published, with several good books available on the subject, depending on which treatments are being considered.
