Good luck with your appointment today, SageMother. Yes, that seems to be a good idea... to know options well in advance. Don't forget to weigh the risks of the silicone, though... NOT as many risks as were reported some time ago, but still present to some degree. Many patients don't really consider the cosmetic issues like whether or not their hair falls out when they are facing something like cancer, so it's good to keep all options open.
