Hi, My 53 y/o daughter was just dx. with breast ca going to bone. She presented in Oct. with neurological sym. and after 3-4 months of extensive work up- MRI, PET, labs they fi nally did bone marrow bx. and found breast cells. Bone scan shows spread to should joints,pelvis and skull. She w jas started on Zometa,Zoladex,Letrozel andPalbociclib. Any comments ? I am so afraid as I don't want to lose her. Barbara. YYYY@YYYY
