I ended up with both the diagnostic mammogram and a 25 minute ultrasound, but the radiologist believes the issue is a benign spot of fibrous tissue. As the ultasound went on and on, I began to sweat it. I started processing how we'd tell the kids, how I would need to make some changes with the business, etc. And after an hour of nervousness, the doctor said it was all okay.
Now it's onto my upcoming hysterectomy, scheduled for mid-November.
