Lung Cancer in the rise with Non-Smokers

"A 2012 French study revealed that from 2000 to 2010, rates of lung cancer among never-smokers shot up an alarming 33 percent. In fact, if lung cancer in nonsmokers was its own category, it would rank among the ten deadliest cancers in the United States. This is in part because the symptoms -- coughing, chest pain, shortness of breath -- are so similar to those of common illnesses; as a result, the disease is often ignored by patients and overlooked by physicians."
