Most of us know someone who has survived cancer, but it is still one of the most frightening diagnoses to hear - lung cancer in particular. In these situations, knowledge is your best weapon against fear. It helps to understand what cancer is and how cancer cells have gone wrong.
The single biggest risk factor for lung cancer is smoking. Secondhand smoke also exposes children and nonsmokers to risk of developing lung cancer.
While the most common symptom of lung cancer is a persistent cough, not every cough means you have lung cancer. Know the risk factors and the symptoms of lung cancer and pay attention to the subtle signs and signals your body sends you. If you don't feel well, talk to your doctor.
