As of August, the American Cancer Society reported that over 170,000 people have been diagnosed with lung cancer. Lung cancer is a formation of tumors in the lung. Also air pollution, and certain occupational practices increases the risk of the development of canerous lung tumors. Clearly, new approaches for early detection and effective therapy are desperately needed. However, significant advances have been made in understanding the basic cellular and molecular biology of the cancer.
