Google knows the answer to your question: https://www.google.com/search?q=stage+iv+breast+cancer+survival . The doctor treating the case (you don't tell if it's about you or about somebody else) surely can tell more taking the details of the case into account.
I'm afraid few members here have personal experience with it. Most are male.
Hi there, I just want to know how much chances of survival are there for Stage IV breast cancer?
