Adams is not alone in doing this. Journalist Xeni Jardin live tweeted her cancer diagnosis two years ago and the long treatment journey. Jardin told the Guardian last year that she wasn’t sure if she would be quite as “sharey” if she could go back in time.

It’s clear that tweeting as compulsively as Lisa Adams does is an attempt to exercise some kind of control over her experience. She doesn’t deny that. She sees herself as an educator, giving voice to what so many people go through. And she is trying to create her own boundaries, flimsy as they might be. She’ll tell you all about her pain, for example, but precious little about her children or husband and what they are going through. She describes a fantastic set up at Sloan-Kettering, where she can order what she wants to eat at any time of day or night and get as much pain medication as she needs from a dedicated and compassionate “team”, but there is no mention of the cost. She was enraged a few days ago when a couple of people turned up to visit her unannounced. She’s living out loud online, but she wants her privacy in real life.

In some ways she has invited us all in. She could argue that she is presenting a specific picture – the one she wants us to remember. “I do feel there will be lasting memories about me. That matters,” she wrote to me in a direct message on Twitter.
