Three years ago my underwent breast cancer surgery, to have her right side of the breast removed.She was doing well untill last year when she started complaining of chest and later general body pains, now she can not sit nor stand for long also she can't walk properly.

Also she has started feeling severe pains at oneside of her abdomen, when I ask her doctor what is actually happening, the doctor says that the cancer has spread into her bones and also the scan results iondicates that she now has a lever problem, please what should I do?
