Hi and congrats,
It kind of depends. I saw them on In October 13, for my initial consult but I hadn't had my second opinion so he just explained what they do and noted what I wanted (radial arm + vaginectomy + clitoral burial). Then said he'd see me again once he had my second letter.
Second appointment was December 2nd and basically they just confirmed I was ready, I assume if you have your second opinion before your consult you won't have to go twice.
I think they try and give you a date there and then but they had nothing till the new year so said they'd phone me.
I had my mastectomy December 18th, so when they offered me January I couldn't take it (you have to wait four months) then they offered me February 14th which again hadn't been long enough. So I knew it would be April at the earliest.
So 31st march (Monday) they offered me 4th April (this Friday)
So it's been 5months since 1st consult, 3.5 from second (if I hadn't needed second opinion) but if I hadn't had chest op I would of had it in January so not a long wait. But I did say I could do short notice I don't know your circumstances.
You have to arrive the day before so I leave tomorrow, this week has been insane!!
Good luck though. All the docs are super friendly, and give you loads of info.
