Is it appropriate to ask someone what stage their cancer has been diagnosed?

Carly Schwartz (Co-Founder) gives expert video advice on: What should I not say to someone with cancer?; Is it appropriate to ask someone what kind of cancer they have?; Is there any one thing I can say to someone with cancer to make them feel better? and more...

To ask someone what stage their cancer has been diagnosed, for me it would depend on how comfortable I was with that person and how close her relationship is. That's a pretty private question. If they seem optimistic, then you can assume that it's an early stage in their cancer, and depending on how they're reacting, if it were a later stage. That's a pretty private issue, I think, and I might use the same discretion with what type of cancer.
