Hi there hopefully they are moving quickly on this surgery. Did they say anything about your chest status? Ground glass like opacities? I'd be asking what they think it is.

Christine is right they can do reconstruction at a later date once everything heals. It sucks that you have to go through more rads and surgery but surgery should get most of it and the rads should finish it off.

Regarding the second opinion not sought, put it behind you - look forward. You are at a top hospital take that to heart. They are looking to cure you... take that to heart as well and hold onto your hope and joy. cancer can be a bitch - it will steal whatever you let it steal. Refuse to give it more than it deserves - which is a swift kick in the butt.
Hugs to you.
