Glad to see you back, HND. That's a lot of steri strips...! Glad your boy had a good birthday. 
Betsy and Kitkat I am no expert, but even if your periods stop completely it doesn't necessarily mean you're through the menopause, as clearly Tamoxifen's buggering about with everything. The only way they can tell is to run blood tests.
And kitkat, I think surgeon will do separately. Mine was keen for the cancer breast to settle first then do the other - rads can shrink skin, etc, etc. In the end I had preventative mx, but she still waited for the other one to settle and even so they still don't bloody match...
Good luck from me too, weebarra. Will be thinking of you.
Night all. Sleep well. zzz
