Sorry to hear about your sister-in law's problem. Triple negative cancer
is a bad disease to have and is usually has a bad prognosis. In her case with the extensive mets present all over the body, it is not advisable to go for such an extensive surgery (hip replacement
). The healing power of the body is also affected in cancer and the body might not be able to sustain such a procedure. It is better that she receives chemotherapy
and radiotherapy can bed given to the sites (bones) where she is having pain.
Hoping for the best.
