Not much detail so I have to make assumptions, which might not be correct.
My guess is the cyberknife treatment would be with a curative intent, and can probably be offered because the cancer is outside of the previous radiotherapy treatment area. It is radiotherapy using very thin X-ray beams from multiple angles, and is ideally suited to zapping up to a few lymph nodes or small bone mets. Being a high power treatment (unlike external beam radiotherapy), hormone therapy treatment is not usually beneficial with it.
Hormone treatment by itself is not a curative treatment, and I presume would be lifelong to delay the growth of the cancer. It would eventually fail.
Given those two choices, I would leap at the chance of a curative treatment with cyberknife. If it doesn't work, you still have the hormone therapy option afterwards.
However, I'm making a hell of a lot of assumptions, and I might be on the wrong path completely. You really need to get this information from the consultant or clinician offering the choice.
