Pathogenesis means the manner of development of a disease. Like many other cancers, lung cancers first begin by the activation of oncogenes, or the inactivation of tumor suppressor genes. Oncogenes basically act to make people more susceptible to cancers, or so it is believed, and proto-oncogenes are thought to turn into oncogenes on exposure to certain carcinogens. The epidermal growth factor receptor manages cell proliferation and tumor invasion. Mutations and changes in this level are responsible for the start of non small cell lung cancer. Chromosomal damage can cause instability in tumor suppressor genes, opening room for cancerous cells to metastasize.
Several genetic polymorphisms—the occurrence of something in different forms—is connected to lung cancer. People with polymorphisms in genes coding for interleukin-1, cytochrome P450, apoptosis promoters such as caspase-8 and DNA repair molecules such as XRCC1 are more likely to get lung cancer after exposure to carcinogens. Here, as in many other things, prevention is better than cure. Caution never hurt anybody, and being prepared, knowing the stuff being fought—namely, cancers—helps out in the long run.
