I received a "call back" in 1999 when I started getting mammograms and it turned out to be nothing. Then in 2003 after I had lost 30 pounds and had gotten in the best shape of my life (with Cathe's help) I found a painful lump (my breasts had obviously gotten smaller). My doctor wanted me to get another mammogram and ultrasound of the area. A spot showed up on the ultrasound, but not the mammogram. Anyway, after a biopsy it turned out to be cancer. I had a lumpectomy, chemo and radiation. I believe getting in shape saved my life because if I hadn't lost the weight, I may have never found the lump (with mammogram) until it was too late. Good luck to you and I hope everything works out for you!!
