What is the chance that someone will survive secondary bone cancer?

Most types of carcinoma metastatic to bone are not considered curable.
Breast cancer is a good bet (depending on the person’s age) in a situation where the primary cannot be identified and the bone lesions are biopsy proven adenocarcinoma. These people may respond with oral hormonal therapy with or without chemotherapy. The key would then be to control the disease with medication and possibly some focal radiation therapy if needed for symptomatic control.

Are you certain this is a malignancy? Is there a confirmed biopsy showing carcinoma? We are greatly hampered by such limited information here. We don’t even know the woman’s age.

If this is an adenocarcinoma, the primary could be a breast cancer, kidney cancer, thyroid cancer, lung cancer, or less likely a GYN malignancy or a GI malignancy. When all testing fails to show the primary, I always treated for the BEST type it could possibly be.

All this testing and searching for the cancer cell type just tells us what is likely to help most. Sometimes you have to guess and try different treatments until you find what works for that one special patient – AND – each person/patient is special. It sounds crude when so much of medicine is scientific these days, but there is still some art to the practice of medicine – and experience counts.
