My mom had breast cancer a few years back and underwent a mastectomy. Now, she has been diagnosed with breast cancer in her liver. The doctors say that it has been there since she had the breast cancer, but it went undetected because her lymph nodes were clean. I am just wondering if there is anyone with a similar diagnosis that can share their experiences with me. As of right now, her only treatment is a pill called arimidex. She has not had any chemotherapy or radiation.
