CT scans to be used to detect lung cancer

SHANGHAI: A new type of X-ray will be added to regular health examinations in a bid to detect lung cancer at an earlier stage, medical officials said recently.

Lung cancer is the world's biggest cancer killer, and over the past 20 years, the death rate from the disease in China has almost doubled.

Speaking at the third national symposium on chest tumors and endoscopes last month, Dr Bai Chunxue said that because the disease does not show any obvious symptoms in the early stages, it is very hard to detect.
