###Human: Is it advisable to carry on surgery for stage 4 breast cancer? ###Assistant: Hi. She needs PET-CT whole body scan to establish the sites of metastasis involved all over the body. Breast cancer only with bone metastasis has a good prognosis. She needs six cycles of chemotherapy first and then reassessment. Surgery is indicated for spine or bone for fixation of fracture and local radiotherapy. Surgery or radiation for breast is not warranted at present. If the spread involves liver, lung or brain other than bone, then prognosis will be bad.
