Christy, There are several people here that have successfully beaten back cancer with a radiation / chemo only (no surgery) treatment protocol. You should not assume anything nor try to guess what might happen. Not even your Grandmother's doctors know for sure. If her doctor used the word Cure then trust in that for now. Surgery has many drawbacks, radiation has many as well. What her dr's are planning will consider the best outcomes compared to statistics. Try not to dwell on them. Just continue to support and care (as you have been doing) and let the doctors do their job. If your grandmother chooses radiation she will need your continued support. There is a lot of information here to help with the problems that might come up with radiation.

Take care.
