Hi there just came across this after working up the gumption to ask google ..My Mum has just been diagnosed 2 days ago with secondary breast cancer in her spine & bones.  She is a young at heart 74 year old.  7 years ago she was diagnosed with stage 4 aggressive breast cancer and had both chemo & radiotherapy immediately and a mastectomy to her right breast.  2 new complete knee replacement  done in the last 18 months now this !? She had lost approx 4 stone in 12 months but I put that down to grieving over the death of my Dad last April.  Consultant told us unfortunately it cannot be treated this time and he was sorry .. what does that mean exactly ?! Anxious Lily
