Genetic findings may help improve smokers' health risk assessment

Published on 08/04/2010
Researchers in the US have discovered a new approach to calculating lung cancer risk in smokers.

Findings published in the journal Science Translational Medicine suggest that while ten to 20 per cent of smokers will suffer from lung cancer, there is currently no reliable method for identifying those most likely to develop the disease.

As a result, diagnosis is often made at an advanced stage of the condition, meaning treatment could be less effective.

However, the latest research has found a genetic mechanism that is activated in the cells that line the airway of smokers with lung cancer, so that a more targeted therapy can be prescribed before the cancer develops.

Lead author of the study Dr Avrum Spira commented: "This represents a critical advance in the field of lung cancer prevention as there are currently no effective strategies among high risk smokers.

"Our work has the potential to help address the enormous and growing public health burden associated with lung cancer."

Exposure to cigarette smoke not only damages the lungs but also has a negative impact on the whole respiratory tract.

In addition to increased health risks and the growing financial cost of the habit, smokers can also expect to pay more for their medical insurance premiums.

Proactive, efficient, and offered me insurance I need. I would say half price I would end up paying if I did it by myself. Many thanks.
