Diseases such as cancer, heart disease and diabetes are some of the biggest health challenges facing the world, experts have said.
The number of new cancer cases worldwide stands at 12 million a year – up a fifth in under a decade.
This is more than four times the annual number of new HIV infections, and 2.8 million of these cancers are linked to poor diet, a lack of exercise and being overweight.
The number of cancers that could potentially be prevented is expected to rise dramatically over the next decade as more people lead sedentary lifestyles and become obese.
The data was released by the World Cancer Research Fund (WCRF), ahead of the United Nations summit on non-communicable diseases (NCDs) later this month. The charity is urging Prime Minister David Cameron to attend to show the UK’s commitment to tackling preventable deaths.
