Hi - my mom was diagnosed with stage 1/2 breast cancer last year. She had the lump removed, no signs of it going to the lymph nodes. She was treated with chemo, radiation and is currently on hercepton. A month ago, her hip started bothering her. She had x-rays, a bone scan and then a CT scan which showed spots in her skull, hip, and two small spots in her liver. Could this all have been metastasizing while she was undergoing treatment like this? She is getting a biopsy of the liver this week but I'm not sure if maybe there is something else she should do. And is this stage 4 then? Does she have the same prognosis as a stage 4 who had no previous treatment?
