According to the Labour Party, Boris Johnson has shown a "chilling" contempt for cancer patients' treatment outcomes.
In response to Johnson's suggestion that wage growth was a more significant indicator of the success of his core policy, Shadow Health Secretary Jonathan Ashworth stated Mr Johnson had no interest in "levelling up" health outcomes
Prior to the Conservative Party conference, Prime Minister David Cameron was grilled by the BBC's Andrew Marr on why there was no way to tell whether those who were worse off under the new strategy were actually catching up with those who were better off.
Forget life expectancy or cancer results; just look at salary growth," Mr Johnson responded.
"Those with lesser incomes are now seeing quicker rise in their wages. It hasn't occurred in at least ten years.
In other words, "levelling up."
According to Mr Ashworth, there would be 19,000 fewer deaths per year if cancer incidence and survival rates among the poorest were equal to those of the affluent.
It was "the most terrifying remarks ever spoken by a Prime Minister denying the relevance of cancer outcomes," Mr Ashworth said. Boris Johnson started his presentation.
"For the poorest people, life expectancy has plateaued. Without increasing health, it is impossible to advance in the game's levels.
That Boris Johnson has nothing to offer but facile words and a lack of deeds has become abundantly obvious.
Following his successful recovery from kidney cancer, Wes Streeting, the Shadow Secretary for Children's Poverty, tweeted: "'Never mind cancer outcomes,' I do." Millions of people feel the same way.
"It's horrifying, insightful, and outrageous all at the same time."
