Pain with Asymetrical Breast

I recently had a mamogram (mammogram) and ultrasound for pain in my right breast. The results came back as asymetrical breast tissue. I was just wondering if that can cause pain. I haven't had as much pain since I've started wearing different styles of bras, but I do feel it every once in a while. Thanks for your help!

Dear 31jp,    Breast pain is a common breast symptom.  The reason for breast pain is not clearly understood, and is not usually associated with breast cancer.  Breast pain is sometimes associated with hormonal variations and is then called cyclical breast pain.  Noncyclical breast pain does not seem to be linked to hormonal variations and is often localized to one area of the breast tissue.  Noncyclical breast pain may or may not be the result of an injury to the breast.  Asymmetrical breast tissue just means there are differences in the tissue from one breast to the other.  The difference could be in terms of size or density or any number of things.  It is difficult over the internet without ability to examine you, your films or to discuss, to know if this finding could be contributing to your symptoms.
