</div> </div> </div> <div class="bColumn"> <div id="definition"><p>Lung cancer is cancer that begins in the lungs, the two organs found in the chest that help you breathe.</p> <p>The lungs are made up of areas called lobes. The right lung has three lobes; the left lung has two, so there's room for the heart. When you breathe, air goes through your nose, down your windpipe (trachea), and into the lungs where it spreads through tubes called bronchi. Most lung cancer begins in the cells that line these tubes.</p> <p>There are two main types of lung cancer:</p> <ul> <li> Non-small cell lung cancer (NSCLC) is the most common type of lung cancer.</li> <li> Small cell lung cancer makes up about 20% of all lung cancer cases.</li> </ul> <p>If the lung cancer is made up of both types, it is called mixed small cell/large cell cancer.</p> <p>If the cancer started somewhere else in the body and spread to the lungs, it is called metastatic cancer to the lung.</p></div> <div id="timesTopic"><div class="story clearfix"> <h3 class="TE">Times Essentials</h3> <p class="aboutTE">Recent findings and perspectives on medical research.</p> <a href="https://web.archive.org/web/20080514071504/http://health.nytimes.com/ref/health/healthguide/esn-lungcancer-ess.html"><img src="https://web.archive.org/web/20080514071504im_/http://graphics8.nytimes.com/images/2008/02/15/health/lungcancer_190_245.jpg" alt="New Therapies Aim at Lung Tumors, Case by Case" height="245" width="190" border="0" class="callout"></a><div class="rightCol"><div class="kicker">Reporter's File</div> <h2><a href="https://web.archive.org/web/20080514071504/http://health.nytimes.com/ref/health/healthguide/esn-lungcancer-ess.html">New Therapies Aim at Lung Tumors, Case by Case</a></h2> <div class="byline">By SHERI FINK, M.D.</div> <p class="summary">Prospects for people with advanced disease are better than just a few years ago.</p><ul> <li class="kicker">Expert Q & A </li> <li><a href="https://web.archive.org/web/20080514071504/http://health.nytimes.com/ref/health/healthguide/esn-lungcancer-expert.html">Lung Cancer, an Equal Opportunity Killer</a></li> <li class="kicker">Questions for Your Doctor</li> <li><a href="https://web.archive.org/web/20080514071504/http://health.nytimes.com/ref/health/healthguide/esn-lungcancer-ask.html">What to Ask About Lung Cancer</a></li> <li class="kicker">Clinical Trials</li> <li class="last"><a href="https://web.archive.org/web/20080514071504/http://health.nytimes.com/ref/health/healthguide/esn-lungcancer-trials.html">Lung Cancer</a></li> </ul></div><div class="clear"></div></div></div> <div class="columnGroup"><div class="story clearfix"> <div class="kicker"> <a href="https://web.archive.org/web/20080514071504/http://health.nytimes.com/health/guides/disease/lung-cancer/news-and-features.html">See All 禄</a> News & Features </div> <ul class="refer"> <li><a href="https://web.archive.org/web/20080514071504/http://www.nytimes.com/2008/04/24/opinion/24thu4.html">To Screen or Not for Lung Cancer: Does It Make a Difference?</a></li> <li><a href="https://web.archive.org/web/20080514071504/http://www.nytimes.com/2008/04/07/opinion/07mon3.html">The Importance of Appearances</a></li> <li><a href="https://web.archive.org/web/20080514071504/http://www.nytimes.com/2008/03/26/health/research/26lung.html">Cigarette Company Paid for Lung Cancer Study</a></li> <li><a href="https://web.archive.org/web/20080514071504/http://www.nytimes.com/2007/07/29/health/29Cancer.html">Cancer Patients, Lost in a Maze of Uneven Care</a></li> </ul> </div></div> <div class="columnGroup columnGroupborderTop "><div class="story clearfix"> <div class="kicker">Reference from A.D.A.M.</div><h3 id="Alternative-Names"><a class="backToTop" href="#top">Back to Top</a>Alternative Names</h3> <p>Cancer - lung</p></div></div> <div class="columnGroup "><div class="story clearfix"><h3 id="Causes"><a class="backToTop" href="#top">Back to Top</a>Causes</h3> <p>Lung cancer is the deadliest type of cancer for both men and women.
