Thank you very much for the response , its great to get some real life experience.
The tumours don't seem too large at the minute and are not impeding him doing anything, but if they get much bigger vet says they won't be operable.
I suppose the biggest decision is whether surgery would actually prolong his life or make no material difference - and I'm really not sure.
I'm also really concerned about post op care, keeping stitches in tact and infection.
I think I will probably hold off and monitor him for a few weeks. I am just not confident he will survive the surgery and if he does, that he will recover enough to prolong his life (It may also be malignant and surgery isn't really going to help much and indeed he will be restricted and confined for a period of time - which he won't be happy with).
No doubt I'll change my mind another dozen times before I finally decide
