Just turned 25..how can this possible?!

So I've been surfing the web and came across this site a couple weeks ago. I finally decided to post my "story" in hopes of some sort of information that Google hasn't scared me with 😔

I'm a mom to 4 kids, I'm married to my high school sweet heart, and I just turned 25 (9/5). In 2014, after years of a VERY heavy, long lasting period, I was placed on the estrogen only birth control pill. After a couple months, I noticed a lump in my left breast. I assumed it was a normal breast change from the new hormones in my system. Well unfortunately, I suffered a minor stroke from the pill, and was taken off of it. Fast forward to spring 2015, the lump has grown. I was honestly afraid to get it checked out. My mom was diagnosed at 38 with IDC. Then again in her late 40's. I finally went in in august (I know I waited way too long) and my dr sent me for an u/s. I went for the ultrasound and figured they would say "oh it's nothing, you're fine." The tech brought in the radiologist, and he explained what benign masses should look like, and how mine was not the typical presentation of a benign mass. So off to get a diagnostic mammogram I went. After that, I was told I needed a biopsy. Well the Army doesn't seem to do anything in a timely matter, so the biopsy isn't scheduled until the 15th. My Bi-rads score is 4. I have an ill defined, not circumscribed mass with hypoehoic, posterior shadowing. The mass was "pointy" and had blood vessels infiltrating it's. The biopsy will take 7-10 days for results. The waiting is killing me. What does all of this mean
