Hmmm. Some deep thinking going to have to take place for you there Barry.
I wouldn't even know where to start on advice and even my thoughts are muddled so goodness know what yours must be like.
Both of those hospitals have fantastic reputations.
Right - now if the Marsden accept that it is suspicious but not cancerous what is the alternative. Are they saying it could be something relatively "mild" and if so and it is treated with the HT, that it will have no effect on it at all and they'll only know it was cancerous if the HT shrinks it?
What effect will the HT have on the rest of your cancer (or your body) apart from the usual unpleasant side effects. Will it help with the recurrent cancer in the prostate?
If you can afford the 68 Gallium PET scan that would then help with a future decision wouldn't it? If it is superior and likely to give a more accurate picture of what is happening, would that not be the best way forward.
At least having had the scan you will know where you stand. You could show the results to both British hospitals, especially the Marsden, if the scan shows that there is something definitely there which needs to be treated ASAP.
Financially perhaps it will be a huge strain and the thought of 3 years HT must be daunting.
Stating the obvious now Barry, sorry.
I hope somebody else will come along and give their input as I can't weigh up those pros and cons for you, never having had any of that treatment.
I wish you well with the decision and I'll be thinking of you.
Best Wishes
Sandra
