Cyst in breast

I recently had my first mammogram in feb. 08. I went to the dr. Today because of
pain in my right breast. The dr. Says i seem to have a cyst because its tiny. She's sending me
for a bilateral mammogram and bilateral ultrasound. Theres no hx. Of breast cancer in my family
and I am 39. Should I be concerned due to the pain I felt. I have one child who's nine.
Thank you

Dear Dee614, 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.  However, without being able to examine you or ask questions, it is difficult to evaluate a situation over the internet.
