According to the American Association for the Advancement of Science (AAAS), it was revealed that the U. S. researchers at Boston University Medical Centre are working on new techniques for detecting lung cancer and benign diseases among the people.

In a study, it was found that among thirty-three smokers, who were kept under observation, 11 were suffering with benign disease and remaining 22 patients were detected with lung cancer.

Lung cancer now can be detected by analyzing the cells from the interior of the nose. These techniques are simple and detect the lung cancer at its earliest stage and then can be treated and cured.

Author, Christina Anderlind, MD, Instructor of Medicine concluded: "In this study we used the same principle as we used in our earlier studies of bronchial tissue, only this time, those methods were used to study nasal cells. Our hypothesis was that the upper airway epithelium of smokers with lung cancer displays a cancer-specific gene expression pattern, and that this airway nasal gene expression signature reflects the changes that occur in lung tissue".

Lung cancer is one of the most common and deadliest cancers and if it is detected in its early stages then the survival rates of the patients increases.
