Lung cancer still the biggest killer

As November's lung cancer awareness campaign continues, medical experts are calling for more emphasis to be given to raising people's attention to the possible causes of the disease, and how it can be prevented.

Lung cancer remains the world's leading cause of death with around 4,000 people dying of the disease daily. In China, that incidence is rising each year and last year lung cancer claimed more than 450,000 lives, according to the health department figures.

Experts say lung cancer is closely connected to a person's lifestyle, with smoking being the No 1 cause. But family history plays a significant part in many cases, as does exposure to cancer-causing agents in the workplace, or in the air outside.
