Just had biopsy, waiting for results

Hello All. I found a lump in my breast 2 1/2 weeks ago. The diagnostic mammogram didn't clearly show the lump, but the ultrasound did. It was rated as a 5 on the BIRAD scale. It is a little over 2cm large in all directions. I should have the results by the end of the week. So far I am keeping it together for the most part. The doctor has suggested that if it comes back as cancer, he wants to do an MRI because I have very dense breasts. Hugs and prayers to all that are waiting and to those that have been diagnosed and are in treatment.
