Lung cancer is the leading cause of cancer deaths worldwide. Most lung cancers do not cause any symptoms until they have spread, but some people with early lung cancer do have symptoms.
Different people have different symptoms for lung cancer. People who smoke have the greatest risk of lung cancer. The risk of lung cancer increases with the length of time and number of cigarettes you've smoked.
Up to 20% of people with lung cancer have never smoked. Many are exposed to other risk factors including second-hand smoke, air pollution and radon gas.
The most common symptoms of lung cancer are:
1) Coughing that gets worse or doesn’t go away.2) Shortness of breath.
3) Chest pain.3) Coughing up blood.5) Wheezing.6) Hoarseness
7) Unexplained weight loss8) Feeling tired or weak9) Infections such as bronchitis and pneumonia that don’t go away or keep coming back
