Waiting on biopsy results- going insane

I’m new here, 46 years old. I had a baseline mammogram at age 36 for fibrocystic disease. At that time there was a small area of dense tissue in the upper outer quadrant of my L breast. Fast forward to 3 years ago, when a 8mm circumscribed mass was seen on my mammo in the same location. They called it a Fibroademona, but it was never biopsied until now. I have been called back every mammo for further testing for the past 3 years. My most recent mammo last week, the mass has doubled in size since last year, it’s irregular, lobular with angular margins. It’s 2cm now, and they are calling it suspicious. I had a core needle biopsy this past Wednesday and am waiting on the results.

Incidentally, earlier this year I had a superficial phlebitis in another area of this same breast that they have no idea why. It was diagnosed as Mondors disease and has since resolved.

I’m a wreck because my mom was diagnosed with IDC a month ago, and prior to this we had no family history. Waiting for these results these past few days have been torture, and now my poor mom is also worrying about me. Trying to think and stay positive but it’s so hard. I have 3 daughters, and if god forbid this is anything, the whole narrative for them changes as well. A lot to think about and I’m going a little crazy right now
