Overview
Cancers are caused by DNA changes that turn on oncogenes or turn off tumor suppressor genes. DNA mutations can be acquired or hereditary. Non-small cell lung cancer may develop by acquired genetic mutation of the TP53 or p16 tumor suppressor genes and the K-RAS or ALK oncogenes as result of exposure to environmental factors such as smoking, asbestos exposure, ionizing radiation, and air pollution, which are considered as risk factors for NSCLC. Hereditary factors in development of lung cancer is poorly understood because they are masked by the influence of environmental factors.
Causes
Non-small cell lung cancer is caused by DNA mutations as a result of exposure to environmental risk factors.[1]
- Genes involved in the pathogenesis of non small cell cancer of the lung include:[2][3][4]
- Activation of EGFR (7p11)
- KRAS (12p12) mutation
- BRAF (7q34)
- HER2[5]
- PIK3CA (3q26)[6]
- ERBB2 (17q12)
- Fusion between EML4 and ALK[7]
- Tyrosine kinase fusions
- ALK (2p23)
- ROS1 (6q22) alteration[8]
- RET (10q11)
