Hi Jane - that is a very complex question where all the responses from us are not going to give you the definitive answer you need. Your medical team is your best source of information.
The type of treatment that you need after surgeries can sometimes influence reconstruction timing.
For me it was a mastectomy (one breast only) with immediate reconstruction; woke up with a small cleavage as a result of having the expander put in place whilst in surgery. I found that hilarious and in time comforting. Come forward a few months and I've had changeover surgery and very happy with the result.
As Anne Marie as eluded already there are lots of posts and information on here as well as your My Journey kit.
It is overwhelming but make a list of questions and be guided by your team.
Good luck with it all
Take care
