Calcification = DCIS? Also, monitoring/watch & wait

The answer to the question "Do I still have DCIS" is "there's no way to know without surgery".

I know that's not the answer you want, but that absolutely is the correct and only answer. No method of screening provides 100% certainty. And unfortunately it's not particularly unusual for areas of DCIS to be larger than what appears on the imaging... so even without any calcifications present, it's still possible that there could be more DCIS in your breast, just DCIS that hasn't yet reached the point of being visible through calcifications. My mammogram showed two large areas of calcifications, and both turned out to be DCIS, but the total area of DCIS found in my breast ended up being about double what the mammogram showed. In my case, I had an MRI that turned out to be much more accurate at identifying the extent of my DCIS, but MRIs are best at catching high grade DCIS vs. lower or intermediate grade.

That's not to say that you have more DCIS than what appeared on your mammogram, but there is just no way to know.

As for monitoring, there a few people who have done that, but most don't hang around here. Hopefully someone doing that will see your post and respond. There are a couple of facilities in the U.S. that have programs to monitor DCIS but none in Canada, to my knowlege. And I believe the U.S. facilities all involve the patient taking Tamoxifen in lieu of having surgery.

Lastly, I am in Toronto and even 12 years ago, I received the ER and PR results on my DCIS after my biopsy - but then I had a surgical biopsy. It's possible that they are waiting for your surgical sample to provide that information; I know some facilities prefer to have the larger sample to do this testing.

I understand your surgery concerns. One possibility might be a lumpectomy with a local or a twilight anesthetic - not usually done but a lumpectomy is a relatively simple/short/easy surgery so it's certainly possible and maybe something you can work out with your surgeon.
