“LUNG FORCE is uniting people across the country to stand together against lung cancer, the leading cause of cancer deaths in the U.S.  Lung cancer happens when cells in the lung change (or mutate). Most often, this is because of exposure to dangerous chemicals that we breathe. But lung cancer can also happen in people with no known exposure to toxic substances. Unlike normal cells, cancer cells grow uncontrollably and cluster together to form a tumor, destroying healthy lung tissue around them. Symptoms usually do not appear until cancer cells spread to other parts of the body and prevent other organs from functioning properly. At this point, it is harder to treat lung cancer.   Smoking poses the greatest risk, but there are others such as exposure to radon and air pollution.Screening high-risk individuals has the potential to drama-tically improve lung cancer survival rates. There are multiple types of lung cancer. Knowing this information can help inform treatment options.”
