DCIS questions

Hi-I have just been told I have pre-cancerous DCIS. All medical staff have told me this is a positive thing. It's still a major blow-I went to the doctor with breast pain and this was picked up through a mammogram-on the other breast! I appreciate that I am lucky and my surgery will be a preventative measure, but it's still tough. I meet with the plastic surgeon in 2 weeks but just wondered if there was anyone out there in the same pre-cancerous situation! Thank you
