I haven't heard a lot about this charity recently but I remember when it was launched, and I know Kris Hallenga did important work. It's very sad.
The BBC article on her passing has this statement from her charity:"Please remember the amazing life Kris led and the things she achieved, but above all else honour her memory by checking your chest... it could just save your life," it added.
I went to the Coppafeel website via Google and was interested to see their concerted effort to use the word "chest" where at all possible. Unfortunate.
