Core BX of 2-cm Mass and Node; Awaiting Results

After having exhausted every single Google link provided about breast cancer diagnosis and treatment, I have been fortunate to find this forum. My story is as follows:

At the age of 45, I finally found my best friend/lover and married (something I swore I would never do again...LOL) on November 24, 2015. He is 53 and has not had children, and I have two from a prior marriage. Given our ages, we decided to start trying immediately, but I had no idea how quickly this would occur! On February 2, the prego tests was flaming positive. On March 16, we had genetic counseling and testing and found out we are having a very healthy baby girl. That is when I decided that maybe that sore lump in my breast was something I should get checked out. I had breast augmentatino, subpectoral, in 1995, and have always has a little problem with my left one. I thought pregnancy and my rapid breast growth and tenderness was contributing to the soreness, but the lump was concerning. Besides, I had a normal mammo and sono 2 years ago, and thought the recommended time is every two years now given normal.

I went in for a sonogram (no mammo as I am 13 weeks pregnant) on Wednesday, 03/30. Immediately, the radiologist came in to talk to me and tell me that it was VERY concerning and also I had a suspicious axillary node. This sent me to mammo with a lead shield over my abdomen. The mammo confirmed the mass, right at 2 cm, hypoechoic, and spiculated - not good. They scheduled me for a core biopsy of the mass and node on April 11. My primary care provider called me at home that afternoon and made an appointment for me to see one of the top breast surgeons in the area the following day, March 31, who in turn got the biopsy scheduled on Friday, April 1 (April Fool!!! ugh). I am recovering nicely from the biopsies and am doing great given the circumstances, but waiting and not knowing until Tuesday/Wednesday is wearing on me. I have to make myself stop doing searches on google and psyching myself out. Not only am I concerned about myself, but about my precious baby girl. The surgeon assured me that the second trimester is the best time to catch this and that chemo is do-able. The oncologist she works with is from MD Anderson, which I take as a good sign.

Now all I have to do is hurry up and wait. I know there is a slim chance this could be benign, but I also am a very realistic person and aware of how slim that chance is. Reading all of your experiences hear has been so helpful and encouraging.....and I so appreciate your sharing them. This is uncharted territory and no one quite gets it. My husband is a rock and tells me we are from strong stock and this is a bump in the road, that we have so much to look forward to, and I believe him, yet....in the wee hours of the morning when I wake up terrified, that is hard to hold onto.
