Firecracker - Here is a controversy you may encounter:
Some docs think that if the cancer has escaped the capsule that surgery is pointless and you should focus on radiation and HT in combination.
Other docs think that even if the cancer has escaped the capsule it can be worth removing the prostate because having a smaller amount of cancer left (called "debulking" as John T. says) seems to help people avoid mets longer, probably because there is less tumor volume to mutate into forms that don't respond to hormone therapy. Dr. Charles "Snuffy" Meyers in in this category (his book is excellent, as John T. has said.) But the more treatments you pile on top of each other, the worse the side effects.
As far as I can tell from my research as a patient, there are smart, respected doctors on both sides of this question. So it can be confusing and difficult for the patient to decide. It can be a personal choice: how much risk do you want to take with the cancer, vs. how much risk do you want to take with side effects of treatment? No doctor can make this decision for you.
If you get the doppler ultrasound you may be able to know in advance if your cancer is still capsule confined, but more likely it is not. If you are comfortable looking up your records and inputting the data into an online calculator you can check out your own odds at the online calculator that Sloan Kettering has posted here:
