Expatriates may be able to lessen the likelihood of them having to finance cancer treatments using international health insurance policies by changing aspects of their lifestyle.
Claudia McVie, chief executive of charity Tenovus, argued 40 per cent of all cancer cases could have been prevented.
Obesity is a significant risk factor in the development of this condition, with modern-day sedentary lifestyles adding to this issue, she pointed out.
Furthermore, the specialist noted smoking is the world's biggest cause of cancer and giving up tobacco is therefore recommended.
"It is extremely important that individuals take responsibility for their own health," Ms McVie remarked.
She explained people can reduce their likelihood of developing cancer by exercising regularly, with walking for half an hour every day known to make a "massive difference".
The expert also suggested that governments around the world could lessen the number of people who die from the disease by enforcing "clear and uniform food labelling".
Programmes relating to diet, exercise and healthy eating should have more funding and it ought to be illegal to market foods to children, Ms McVie argued.
"This will all save money in the end," she stated.
There are numerous symptoms of cancer and while some of them are shared with other illnesses, it is important that individuals visit a healthcare provider to have them checked out.
One of the most common indications is a lump, which can be located anywhere on the body.
Other signs that a person could have cancer include hoarseness, breathlessness, coughing and blood in the phlegm, as well as changes to bowel habits.
Unexplained weight loss, peculiar moles and unusual bleeding, such as in the urine or vomit, should also be checked out by doctors.
World Cancer Day takes place tomorrow (Saturday February 4th).
Organised by the Union for International Cancer Control, this event aims to lobby for change, educate the public and raise awareness relating to the ailment.
