I assume your urology department has said it is up to you to choose? In the circumstances you have outlined here, I think if you were my dad I would be encouraging you to go straight for HT with radiotherapy for the following reasons:
- they have already advised that the surgery might not get it all
- the wait for surgery seems excessive (presumably they are saying this is down to Covid?)
- if they are concerned about getting all the cancer out, they may also be proposing that the op will be non-nerve sparing which means that erections may only be possible with injections or a vacuum pump (have they said whether the op would be nerve sparing?).
- the appendectomy scar may mean that the surgery has to be open rather than keyhole, in which case you would be in hospital for longer and the recovery is slower (have they said that keyhole is possible?)
- if you opt for RT / HT the hormone treatment can start almost immediately so the cancer is controlled and cannot spread
- it is normal to be on HT for 3 - 6 months before the RT starts, by which time we can all hope that Covid risk is much lower
The downside is that you have already had some of your bowel removed - only an oncologist can tell you what implications that would have on your suitability for RT - have you seen an oncologist yet?
