Almost 4.45 million cancer deaths in 2019 were caused by smoking, drinking, being overweight and other known risk factors, a new study suggests.
The research is the first to estimate how a list of 34 risk factors contributed to cancer deaths and ill health globally, regionally and nationally, across age groups, for both sexes and over time.
According to the study, 4.45 million represents 44.4% of all cancer deaths across the world. However, the data suggests the UK number of cancer deaths from the risk factors was above the global average, at 49.7%.
