How many progress to Stage IV?

PamelaMary,

Your question was a good one. I took a harder look at the numbers and learned a lot.

Susan G. Komen posted this, but the links to support the numbers are inop:

The most important thing to remember is that survival for metastatic breast cancer is highly variable. Although the average length of survival for women with metastatic breast cancer is in the range of 2-3 years, this is an average and does not predict how long any one person may live.1 About 25 percent of women with metastatic breast cancer live more than five years after diagnosis, and some women live 10 or 20 years beyond diagnosis.2 It is also important to note that these survival estimates are based on women diagnosed before some of the newer treatments for breast cancer were available. Current treatments may mean improved survival for women diagnosed today.
