Radiation - short course or long course

Thank you all so much for your responses. It's such a lot to process in such a short time. I feel like both options have merits, and obviously, human nature being as it is, the short course is very tempting. I keep reminding myself that at the end of the day the goal is to prevent recurrence - there is no perfect choice. My husband is overseas this week, I guess I'm just feeling a little fragile. My friend offered to come with me to the appointment but I declined. Silly me!  Obviously not as tough as I thought I was. Again, thank you for your support. It means a lot.
Footnote: my lovely surgeon rang me back and talked me through everything. I'm feeling a lot better now and confident in my decision
