Your reports are suggestive of a cancer / malignancy which would be a Stage 4 disease considering it have already involved multiple bone sites and liver sites . We have identified from where this cancer started , that we will be able to identify based on the further imaging , and a biopsy of tissue probably from your liver if no other site of lesion is found . Together with the blood reports you have send before , considering this a stage 4 disease - our intent of treatment will be to give your mother as much as possible quality of life and control the disease to the best of facilities we have - we will be calling such treatment palliative treatment . With the use of modern targeted/immunotherapy drugs even in advanced stage we would be able to give treatment to your mother . To decide on what type of a tumour this is , and what is site of origin , further imaging and tissue diagnosis (biopsy ) is required .
