called back on mammogram

Hello, my first time on this site.  I was called yesterday to come back tomorrow for another mammogram on my right breast and sonogram on both breasts.  It has scared me to death.  I am 59 years old and have no history of breast cancer and have up to this point always never had any trouble with mammograms.  Something about right assemtry and architectual distoration.  (spelling probably wrong) I don't know but I am so worried.  Anyone out there with a similiar diagnosis?  Please keep me in your prayers.    Thank you.

My news was good.  My second  mammogram still showed a place on the right breast.  They did the sonogram and determined it to be tissue overlapping and said that to come back for another mammogram in a year.  The doctor did say that any medications  I  take, and I take a lot for the heart, the meds can cause changes in your breast tissue.  This has scared me so much that I don't even know if I'll go for another mammogram.
