you appear here apparently having made your treatment choice? We all hope that you have done all the research that we would have done prior to doing so, we who are in the know now, would have done, with hindsight.
Your op is due in 9 days but until you go under the anaesthetic you can still change your mind.
Maybe you might like to give the details of your diagnosis and staging thus far? Give all the information you have and people here will give a view on where you are and what you mighty have as options?
Nobody here or elsewhere should tell you what to do or persuade you what to do, they will not have to live, or die prematurely, from the consequences. And those here who have undergone treatment and suffered or survived, maybe excelled, that does not necessarily mean that you will either suffer, survive or excel. Everyman recovers in their own individual way.
There will be some who will say "Oh, my partner had this and he regrets this bitterly now cos he needed extra "blah" treatment, curses the day he made that choice, FFS what was he thinking off, what a muppet, etc etc? But they don't know what the result may have been had they gone on a different course.
There is no CLEAR winner in the treatment stakes. Read this again. THERE IS NO CLEAR WINNER IN THE TREATMENT STAKES!!! IF, there was, all the others would have been discontinued by the NHS. Simply a fact of life, and economy.
I would suggest to you that if anyone attempts to guide you to a particular treatment, ignore them. As in feedback you ignore the top 10% and the bottom 10%. Similarly ignore the most vehement and the least enthusiastic suggestions.
BUT, above all read well, research thoroughly, and then make YOUR decision, AND go for it wholeheartedly, 100%.
There are no second chances mate. No looking back and reconsidering.
