Isn’t metastatic bc automatically stage IV? I thought they were the same thing?

Hmm the American sites have always varied a little in how they stage BC. Wonder if it effects what their health insurance will cover, pay for?

Good point Belinda. I’ve been on the American forums just a couple of times and noticed that some of them describe their mets as " stage 2 with spread to bones" or stage 3 with lung and liver mets"
Wondered why they were not calling them stage 4.
