Hi Trinny, and welcome to the forum.
Please don't worry about the wait. This question comes up quite a lot here and it's quite common to have waits of several weeks. If the doctors felt it was urgent, you'd be seen quickly.
DCIS means the cancer has not moved out of the ducts. My surgeon said it can sit in there for years and never move.
I know saying 'don't worry' when we talk about cancer is silly, because it's almost impossible! But I don't think you should be alarmed by the wait at this stage. Try to keep busy, distract yourself as best as you can, and if you have any questions in the meantime, don't hesitate to come here and ask. Big hug, K xox
