This is such a great point! It's unfortunate especially with this cancer that the stigma of it is a hard conversation to have. I would suggest for those who want answers to state that at a later time, you can explain a little clearer and maybe direct them to an organization website that can give more details, so when you meet again they get it without you touching too hard on the explanation.
Wishing you and your friend the very best!
