In the future, expatriates could use international private medical insurance policies to discover their risk of suffering from lung cancer, following a new study that confirmed the existence of a genetic susceptibility to the condition.
The research, which was published in the Journal of Thoracic Oncology from the International Association for the Study of Lung Cancer, found a number of genes that appear to impact the likelihood of a person developing the ailment.
Scientists examined the genetic profile of 716 Japanese patients who had developed the illness and 716 people from the region who had not.
Previous investigations had shown Asian people who have lung cancer are more likely to be non-smokers than those with the condition in the West, as well as having a greater chance of harbouring epidermal growth factor receptor mutations.
Tobacco smoking is known to significantly increase a person's likelihood of suffering from this form of cancer and quitting the habit causes this risk to go down immediately.
