Thanks for writing in.
Secondary bone cancer
in a female is mostly from breast, lung, kidney or thyroid. Pelvic tumors
spreading to bone is rare. The pelvic tumor may itself be a secondary.
She needs CT scan thorax and abdomen, mammography
and thyroid ultrasound
to locate the primary. A few special tests (immunos) on the biopsy can also tell something about possible primary.
The prognosis depends on the primary site. For example, it is better in breast or thyroid.
She also needs radiation to the larger skull deposit.
