breast calcifications and architecture distortion

It is normal to be fearful. i remember having time in between, but no history of breast cancer as you have in my family that i knew of at the time. My tumor was big, so i moved to the diagnostic within a few days. The fact you are not being rushed appears good. Whatever you have will be found and steps taken. The best thing is you completed the mammogram have had one test and the next one to do. I had an MRI withing a week of the ultrasound. Maybe yours will still be like your sisters and slow growing. Keep coming back here for support. We get it.

Yes, as katgob said, jobon - we certainly get it.
I actually began my journey just like yours. However in 2023 - despite my dense breasts and microcalcifications - my mammogram (followed by routine sonogram) was determined to be fine.
In December 2024 (my annual mammo) I was told - exactly what you were told. I too was very nervous but somehow in an odd way, calm. I needed 4 biopsies - 2 in each breast. I knew in my heart "something" was going to be found and it was. Long story short...it was all early stage. Lumpectomies were out of the question since always followed by radiation and I already had a serious heart condition. I could not chance more scaring on my heart. At age 70 I had a bilateral mastectomy & decided on no implants (I didn't need "possible" further complications down the road especially b/c of my age and other medical issues). Everything turned out well. I had lots of support and was accepting (or perhaps even in a denial, which is not a bad thing!) of it all...I had no symptoms of BC and absolutely no family hx. of BC - no cancer at all. This time is the most difficult for you. The "not knowing" is very hard to cope with. Since your follow up is in 2 weeks, that also tells me this is a good thing. Do all you can to remain calm at this time. Whatever it is you do for relaxation and distraction, do it. There is nothing to do right now but wait. It truly is one step at a time. Your mind can only handle that...please don't immediately go into the future. You have no idea how this will play out! We all have been in your shoes...some of us got the diagnosis and others did not. You simply don't know. Emotional stress will not help but I know easy to say - hard to do. But do try to live one day at a time, step by step. Please keep in contact with us for support. Blessings.

I would recommend reading, The Smart Woman’s Guide to Breast Cancer. She (Dr. Jenn Simons) will alleviate your concerns so you can make good decisions.

Remember even if DCIS, that is PREcancerous. I’m not downplaying that diagnosis but it is important to understand that there are many women at this moment walking around that do not even know they have precancer and may never turn into cancer. Low grade doesn’t even show up typically on an MRI—so I have been told many times by multiple doctors. Some studies are now saying DCIS is over treated. Hang in there and don’t let scare your quality of life away
