He said Ms Adams was "the standard-bearer for an approach... that honours the warrior, that may raise false hopes, and that, implicitly seems to peg patients like my father-in-law as failures."
Ms Adams - and many others - were outraged. "I am alive. Do not write me off & make statements about how my life ends TIL IT DOES, SIR," she wrote on Twitter. Other commentators jumped to her defence. Writing in the New Yorker, Meghan O'Rourke criticised Mr Keller for treating Ms Adams' "personal choices as an occasion for moral legislation".
Ismena Clout, who has incurable secondary breast cancer and blogs for The Independent, said that while she disliked the "fighting" cancer metaphor, patients had a right to talk about and act on their condition in their own way.
"When you've got someone going through such an horrific time... finding the energy to write about it, to help educate and raise awareness, then that should be commended, not derided," she said.
Dr Emma Pennery, clinical director at UK charity Breast Cancer Care agreed. "We tend not to use the "battle" terminology. It implies you have control of the battle - that's not a realistic expectation," she said. "But there is no way you can say one way of speaking about cancer is right and one way is wrong."
@adamslisa: The patient's tweets
Articles about "defiant patients" who "refuse" to accept prognoses continue to reinforce the BS that attitude determines long term survival
Very rough day here. Dizziness, weakness, pain. Need the tumors to shrink for relief. That will take time:chemo and radiation
If any of my healthy friends lived this life for 5 minutes their heads would explode. I know mine is ready to and I live it every day now.
Why is she tweeting if it hurts so much?" I am sure people ask. It helps to distract me especially when I am alone (it's 6 AM here)
