If her breast cancer has spread to her bones and to her liver(so she does NOT have bone cancer, she has breast cancer that has spread to her bones) she is in principle a stage 4(IV) breast cancer case which at present is incurable. Even though incurable it is often possible to control the cancer with chemo therapy - though for the time being that is impossible in her case due to low blood platelets - or if her cancer was hormone receptor positive - of which I know nothing - with(anti)hormonal therapy or it may also be controled with radiation therapy(which also can be complicated by her low blood platelets). Actually if her symptoms from her hips are so severe I'm astonished that local radiation therapy there has not been suggested in her case. If indeed she is starting to become jaundiced her liver lesions must be quite severe. The need for regular blood transfusions also points in the direction of a quite severe case. All these things indicate that her condition is quite bad. And her prognosis is therefore also probably bad unfortunately. So unfortunately you probably have to prepare for the worst. I'm sorry I have nothing better to tell you! By the way, pardon this my question but what you wrote made me curious, was she only 15 when she got married?! Where do you live?
