Expatriates concerned about their health might want to head the advice of Dr Mark Matfield, scientific co-ordinator at the Association for International Cancer Research.
Dr Matfield has explained that the simple way of reducing the risk of developing cancer is to quit smoking.
"Ninety per cent of lung cancers are caused by smoking and it is one of the most difficult types of cancer to treat effectively," he explained.
"Smoking has also been linked to higher rates of more than ten other types of cancer."
Expatriates living in Denmark might be particularly keen to heed the suggestion after the latest research from the World Cancer Research Fund revealed that Denmark is the world's cancer capital.
Indeed, around 326 people in every 100,000 in Denmark develop cancer each year.
While good diagnosis methods are partly responsible for the high rate, extensive smoking and alcohol consumption were also identified as major risk factors among people in Denmark.
