A health expert has stated that the best way to lower your risk of developing cancer is to quit smoking.
Dr Mark Matfield, scientific co-ordinator at the Association for International Cancer Research, said that around 90 per cent of lung cancers, one of the hardest cancers to treat, are caused by smoking.
"Smoking has also been linked to higher rates of more than ten other types of cancer," he added.
The second largest risk factor, according to Mr Matfield, is obesity, followed by alcohol intake and diet.
Earlier this week the World Cancer Research Fund revealed that Denmark has the highest recorded rate of cancer in the world.
This is partly due to the fact that the country has good diagnosis methods. However, high levels of smoking and alcohol intake have also been held to blame.
A total of 326 people out of every 100,000 in Denmark develop cancer each year, the report confirmed.
