Hi Rene, a pretty crappy birthday gift I'd agree, but great that it has been caught early.
I'd just add that it might be good to have a chat with your breast care nurse before Friday to talk about some of those decisions and explain some of the foreign language we're suddenly having to get our head around. Sometimes it just helps to verbalise some of those questions with someone who can help and guide you in the right direction.
The Guide was invaluable throughout my treatment (I'd just dip in & out of the relevant sections as trying to take it all in at once was overwhelming and used it to form my questions for whichever specialist I was seeing), and of course nothing beats talking to those who've been there and can offer some words of support and understanding, so feel free to post any time you have a question, are confused or just want to vent.
Best of luck with your next steps and decisions. Jane xx
