Lung Cancer – Signs And Symptoms Associated With The Disease



Lung cancer is a type of cancer that begins in the lungs. Your lungs are two spongy organs in your chest that take in oxygen when you inhale and release carbon dioxide when you exhale.

Lung Cancer Facts

  • Lung cancer is the number one cause of cancer deaths in both men and women worldwide.
  • Cigarette smoking is the principal risk factor for the development of lung cancer.
  • Passive exposure to tobacco smoke (passive smoking) also can cause lung cancer in non-smokers.
  • The two types of lung cancer, which grow and spread differently, are small-cell lung cancers (SCLC) and non-small-cell lung cancers (NSCLC). Medical professionals also refer to them as small-cell lung carcinoma and non-small-cell lung carcinoma.
  • The stage of lung cancer refers to the extent to which cancer has spread in the body.
  • Treatment of lung cancer can involve a combination of surgery, chemotherapy, targeted Tumors, immunotherapy, and radiation therapy as well as newer experimental methods.

People who smoke have the greatest risk of lung cancer, though lung cancer can also occur in people who have never smoked. The risk of lung cancer increases with the length of time and the number of cigarettes you’ve smoked. If you quit smoking, even after smoking for many years, you can significantly reduce your chances of developing lung cancer.

Lung cancer typically doesn’t cause signs and symptoms in its earliest stages. Signs and symptoms of lung cancer typically occur only when the disease is advanced. Those symptoms may include:


  • A new cough that doesn’t go away
  • Coughing up blood, even a small amount
  • Shortness of breath
  • Chest pain
  • Hoarseness
  • Weight loss without trying
  • Bone pain
  • Headache

You can reduce the risk of lung cancer if you:

Don’t smoke.

Talk to your children about not smoking so that they can understand how to avoid this major risk factor for lung cancer.

Stop smoking.

Quitting reduces your risk of lung cancer, even if you’ve smoked for years. Talk to your doctor about strategies and stop-smoking aids that can help you quit.
