The leading risk factor for developing lung cancer is a history of smoking. Experts estimate roughly 80 percent of lung cancer deaths are a result of smoking, including cigar smoking and secondhand smoke. Some additional lung cancer risk factors include:
Exposure to radon
Exposure to asbestos
Exposure to other carcinogenic workplace chemicals or minerals
Family history of lung cancer
By the time most people with lung cancer have symptoms, the disease is at a more advanced stage. However, some people do develop symptoms with early lung cancer. These can include:
Coughing up blood or rust-colored phlegm
Shortness of breath
Feeling weak or tired
Persistent and/or recurring bronchitis or pneumonia
If you experience any of these symptoms, visit your doctor at St. Luke’s Health.
