I had a 2.5 mass I discovered myself. I was estrogen positive. The cancer had already spread to my nodes, so they were all removed. My tumor was on top of my breast, nearly under my nipple. I had a lumpectomy, chemo, radiation. 7 years ago, and all is well. I do still check myself (since a mammo missed the tumor), and get mammos.
Please come back to set us know what you find out. We do come to the site, but don't always see newbies, so we'll be praying for you!
