LUNG CANCER-PART III

     Types of lung cancer

Lung cancer is caused by the uncontrolled growth (proliferation) of abnormal cells inside the lung. There are two main forms of the disease, non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) (Barzi and Pennell, 2010).

LUNG CANCER-PART II

Despite most of developing countries gave attention for communicable diseases; the global burden of non-communicable diseases like cancer continues to increase largely because of the aging and growth of the world population alongside an increasing adoption of cancer-causing behaviors in economically developing countries (Jemal  et al., 2011).

LUNG CANCER -PART I

The global burden of cancer continues to increase largely because of the aging and growth of the world population alongside an increasing adoption of cancer-causing behaviors in economically developing countries. Based on the GLOBOCAN 2008 estimate, about 12.7 million cancer cases and 7.6 million cancer deaths are estimated to have occurred in 2008; of these, 56% of the cases and 64% of the deaths occurred in the economically developing world (Jemal  et al., 2011; American Cancer Society, 2007).
