Thanks to my sister, my breast cancer was caught early. My sister felt a lump for several years but her doctor assured her it was nothing. Turns out it was breast cancer that had spread to her lymph nodes. Because of her cancer, my doctor told me to start doing mammograms as soon as I stopped breast feeding my youngest. My first mammogram was fine. My second was not. I had a lumpectomy in November 2008 and a second in December 2008 (they didn't get it all the first time). Radiation came in February and March. So get out there and do your mammograms. If not for yourself, then do it for your sister.
