Diagnosis of breast cancer - spread to ribs and spine -biopsy pending. mam on 11/12 neg. i feel fine. is it still possible that this is stage 3 not 4?

Wait 4 biopsy result: What imaging did you have to evaluate the bone? To disprove that those lesions are not metastatic disease- it requires biopsy to all those lesions and to demonstrate that all biopsies taken from those lesions are negative. My suggestion is for you to wait for the biopsy result- i assume the biopsy was done to one of those bony lesions, correct? I hope they got enough tissue from the right location.

No: Susan: unfortunately, once there is documented and confirmed spread to the bones or other areas distant from the breast, it is considered stage 4. The bone disease can be managed and halted where it is with treatment so definitely follow the treatment plan your doctor prescribes.
