Cancer treatment and lifestyle changes need to be discussed if lives are to be saved, the World Cancer Research Fund (WCRF) has warned.
According to the group, the number of new cancer incidences could be cut by 2.8 million a year if people adopted an improved diet and healthier lifestyle.
Smoking is a major contributor to cancer risk but Professor Martin Wiseman, adviser at the WCRF, has stated simple changes can be made. He said people need to be "physically active" and maintain a healthy weight. This, allied to a "plant based diet with plenty of wholegrains, vegetables and fruit, and modest amounts of meat and dairy, without too much alcohol, salt or processed meat", will see risks reduced.
Professor Wiseman added that if nothing changes, there will be an inevitable rise in obesity and inactivity around the world, which will ultimately lead to more cancer incidences.
The WCRF has said the first ever United Nations summit on non-communicable diseases, which begins on September 19th in New York, is a "once-in-a-generation" chance to prevent a "public health disaster".
Worldwide, there are 12 million new cancer cases every year, according to WCRF figures.
