I AM FINE!!!   I had my mammogram and the doctor looked at my new images immediately.  She said I definitely needed the ultrasound.  My u/s appointment wasn't until 4:30 (my mammogram was at 1:00), but they were able to get me in at 2:00.  I waited in the waiting for 40 LOOOOONG minutes.  Of course, I imagined the worst.  I was on the verge of tears the entire time.  I finally got to the examination room and the u/s tech looked at me for at least 20 minutes.  She said "I just can't find anything, anywhere".  She went to get the doctor and the doctor looked for a good 10 minutes and said I was perfectly healthy; no cysts, no tumors, no growths, whatsoever.  She said it has to just be an area of thickened tissue.  I am so relieved!

Thank you, everyone, for your prayers.  I appreciate your positive thoughts more than I can say.
