Hi Rupert,
Many on the forum have had surgery and would do exactly the same thing again, many have had radiation and stand by their choice, so usually it is not a matter of one being better than the other, but rather one suiting the needs of the patient, their tumor, and their personal preference better. What seems most important to me, though, is that whatever decision you make is YOUR decision and that you are at peace with it. That confidence really is critical to helping you face your treatment with a positive, got-my-ducks-in-a-row, torpedo-ahead attitude. By the time my surgery date came, wild horses could not have stopped me. I was sure and I was READY. If you need more time, to be sure and ready, take the time, and talk to other docs. Once you're sure that the treatment is the right one for you and that you've got the best qualified doctors working on you that you can possibly find, you'll be able to give your trust to them, and will be confident that whatever outcome you end up with will be the best you could have gotten.
