Two-thirds of cancer mutations are random and unavoidable, scientists claim - ScienceAlert

 “Almost two-thirds of cancer mutations are caused by random DNA-copying
errors during cell division and are impossible for us to avoid,
regardless of lifestyle and the genes we inherit from our parents,
according to new research. . . . If the findings end up being accepted
by other cancer researchers, the idea that randomness – in other words,
bad luck – is more significant in causing cancer than other contributing
factors could amount to what Tomasetti calls ‘a complete paradigm shift
in how we think about cancer and what causes cancer’.”
