No one knows because the system for tracking longevity does not track recurrence only episodes of cancer. There are also several different subtypes of cancer and different cancers can be more or less aggressive. Just do your best to live every day the best you can.

Barbara is right, Dr Google is not your friend.
I work as a nurse in breast cancer clinic. He had a patient stage 4, Mets to liver and bones, she lived 14 years with high quality of life. Another who had brain Mets over 5 years, doing well.
Every patient is different. Really, only God knows.
Wishing you well!

Every woman is different, every cancer is different. I've had stage 4 Breast cancer for 3 years with 3 different bone Mets. As of last October, no metastases to organs yet. Don't google stats because none of us is a statistic. Take one day at a time and don't over worry about how much time you have left.

I am on 9 years MBC with bone mets. It is scary, but take it one day at a time. Iam not worried about how long iam going to live. Make your life the best it can be, do what you can and don’t worry about what you can’t do.
Have a good week.

Agree, definitely sage advice from these ladies' living life to the fullest with MBC. Living your life, your way, "Doing you" is important! Positivity, attitude, and outlook all count!
No one knows when exactly the end will come. Live your life to the fullest until it's over on this earth because it continues!
