Overview
The direct cause of lung cancer is DNA mutations that often result in either activation of proto-oncogenes (e.g. K-RAS) or the inactivation of tumors suppressor genes (e.g. TP53) or both. The risk of these genetic mutations may be increased following exposure to environmental insults.
Causes
- The direct cause of lung cancer is DNA mutations that often result in either activation of proto-oncogenes (e.g. K-RAS) or the inactivation of tumors suppressor genes (e.g. TP53) or both.[1][2]
- The risk of these genetic mutations may be increased following exposure to environmental insults, which are regarded as risk factors that predispose to the development of lung cancer.
