What You Need To Know About Lung Cancer

Oct 17

Lung cancer is considered the leading cause of cancer deaths in the U.S. According to the Centers for Disease Control and Prevention, the disease killed more than 150,000 people in the country in 2012. You are at highest risk of lung cancer when you smoke. Other risk factors associated with lung cancer are exposure to second hand smoke, asbestos, and radon gas. You may also be at risk if you have a family member who has the disease.

Apart from those mentioned above, you increase your chance of getting the disease by being constantly exposed to polluted air. Unfortunately, not all vehicle companies are sincere in their fight for a cleaner air. Volkswagen deliberately sold vehicles with a special “defeat device” to lower pollutant levels during an emissions test in order to cheat it. The auto maker admitted that it sold around 11 million of such cars worldwide.

Signs and symptoms of lung cancer seldom occur during its earlier stages. As the disease progresses, you may experience persistent cough, chest pain, hoarseness, and wheezing. You may also cough up blood, experience headaches, and unintentionally lose weight.

If you think that you are at risk of lung cancer and are experiencing any of its symptoms, visit your physician immediately for a test. After a complete physical exam, he may recommend imaging tests, such as computerized tomography (CT) scan and magnetic resonance imaging (MRI) to see potentially cancerous lesions. A sample of a lung tissue can also be obtained for testing. If you have a productive cough, a sputum test may also be recommended.

Finally, you may also consider testing for lung cancer even if you are healthy, although you still need to consult with your doctor to know its possible advantages and disadvantages.
