After more mammograms and ultrasounds, it was determined that the lumps were probably just benign cysts and no need for further testing at this time. However to be on the safe side I'll be rechecked in March. So I can breathe a sigh of cautious relief ;) Wish they would have left the word "probably" out of their diagnosis but I understand they need to CYA.
So thanks for all your well wishes and prayers. They were greatly appreciated.
