I had a clear mammogram 5 weeks before I found a palpable lump. I had no dcis. My dense breast tissue made it very difficult to be detected. It was due to this I had a bilateral mastectomy as I didn't think I could ever feel safe.
I believe in future they would also do ultrasound with mammogram which increases it's accuracy with pick up. Perhapa a bi- annual mri might be worth considering but I don't think they pick up dcis very well either. I guess it's something to discuss for future thinking. However it won't change your treatment today. So focus on that and have those discussions with your breast surgeon along the way. You will be having many more appointments. Kath x
