Hello again, Melissa6666.
Thank you for posting.
We cannot see nor can we interpret your scans. So, specific questions based on your scans and examination should be discussed with your doctor. I can give you general information only.
Breast asymmetry refers to when one breast is a different size or shape than the other. A mammogram or breast cancer screening may show asymmetrical breast size or density. There are a number of reasons why a woman's breasts can change in size or volume, including trauma, puberty, and hormonal changes. Another cause for asymmetrical breasts is a condition called juvenile hypertrophy of the breast. Though rare, this can cause one breast to grow significantly larger than the other.
Your doctor can help you further.
