Can you tell me what is the life expectancy of metastatic breast cancer?

It varies.: In general, less than 20% of women diagnosed with metastatic breast cancer will be alive 5 years after their diagnosis. However, this statistic may vary quite a bit depending on which organs the cancer has spread to and which drugs the cancer may be sensitive to.

It depends: There are many types of metastatic breast cancer. Life expectancy depends on the type and the location. Er+ breast cancer that has spread only to bones has a life expectancy of years, even 5-10 years. Er- breast cancer has a much shorter life expectancy. In general, breast cancer in organs (lung, liver, brain) causes death sooner than breast cancer in bones only. Ask your oncologist.
