Hi there! This just happened to me too. I had a mammogram done because my mom had breast cancer at 43 (I'm 34) The mam. found a lump and I was called back in for a ultrasound, then I had a biopsy done. The worst part was definitely the wait for the results. I expected the worse, because the dr. couldnt really tell if it was a tumor or a cyst. I just needed a yes or no! It came back benign and is a complex cyst that will be monitored. Stay positive, the waiting and not knowing is the worst part. Good luck and keep us posted!
