Welcome to the blog, @Rachelz ... it may 'seem overkill' just now ... but the more tests that you have done now, the better, I reckon! It will give them a much better 'picture' of your situation as at 'now' ..... and also a baseline to compare with further down the track & fine tune your treatments! So I reckon you are actually very lucky that your surgeon has requested these xx
Keep this thread going as you proceed thru your tests & surgery & pathology & treatment plan .... you'll be able to look back on this next year, I reckon & go 'WOW' .... what a roller coaster ride!! xx
take care & all the best
