Sorry you have joined us with breast cancer but welcome. Have a look up the top bar at understanding breast cancer. In there should give you an idea of what to expect and if your breast screen hasn't already ordered one for you order yourself the free journey kit. It has heaps of help for you. You should have a breast care nurse contacting you soon too who will act as your liaison between all the specialist and tests so you aren't doing it all alone.
As to how long it will all take? I would say allot six months of this year away to treatment. I was diagnosed early October and I still have a few more weeks of treatment yet. There is no diabolical rush with all the treatments and if you aren't quite ok with it or ready your doctors and breast nurse should be able to help you along the way.
If you click any of our names in posts, it will take you to our profiles and you can read all our posts. I think mine starts pretty close to day one and my cancer was fairly small and not that scary so you are welcome to read mine. I try to up upbeat with my posts and hide my depression which is manageable most of the time but lots of times I have been just plain peeved off and that's putting it mildly. I try to dampen that down in my posts too or I might get banned for language. Seriously we all get a flood of emotions and aren't quite sure sometimes how to deal with it but somehow we all do get through it. Hugz XXXXXX
