Lung cancer can be detected through blood test

Early symptoms of lung cancer can soon be discovered with a simple blood test. British researchers have created a new kind of testing that can identify the early stages of the disease and even predict where precancer tumors can develop.

The findings of Friday and '%smation published in the magazine Disease Models and Mechanisms can be crucial to beating the disease, experts say. Lung cancer is the leading cause of cancer - related deaths because it is very difficult to diagnose and often appears later when it is more difficult to treat. If a lung tumor is discovered early, surgery can easily be removed to prevent its spread to other parts of the body.

Otherwise, lung cancer is officially the leading cause of cancer - related deaths. Each year in Great Britain, 46,400 lung cancer cases are recorded. Only one in 10 patients lives up to five years after diagnosis.
