Thank you for the detailed explanation. I will let you know the outcome after my test, hopefully all will go well.
Hi Annie,
Asymmetry in the breast is really a non-specific finding and does not necessarily mean something bad.It could be due to many benign factors such as fibrocystic breast condition as well as breast density.Also it's possible that the mammogram pictures might not have been clear,due to swollen breasts when you started your menstruation
Being called back for a spot compression mammogram,is not at all unusual.When a mammogram shows an abnormality,the first thing is to do, is to have a spot compression mammogram that will focus on the area of concern for a better view. Sometimes the breast tissue can fold over on itself causing a density or shadow to appear.A spot compression will often smooth out the tissue and the abnormality will disappear confirming that all is fine.If this happens,an Ultrasound may not be needed.
Please don't worry,I've read so many cases such as yours which turned up just fine.
Good luck and best wishes...
