What You Need to Know About Lung Cancer

No. 1 cancer killer is also one of the most preventable

More Americans die each year from lung cancer[link with www.nlm.nih.gov/medlineplus/lungcancer.html]than from colon, breast and prostate cancers combined. The American Lung Association estimates that more than 160,000 lung cancer deaths occurred in the U.S. in 2007 and another 175,000 new cases were diagnosed.

Many lung cancer deaths are potentially preventable. Smoking accounts for nearly 90 percent of lung cancer cases. Risk of lung cancer increases in proportion to smoking history, yet smokers can reduce their risk by quitting. Within 20 minutes of his or her last cigarette, cigar or pipe, a former smoker’s health begins to improve.

People who don’t smoke but who breathe the smoke of others may also be at a higher risk for lung cancer. Non-smoking spouses who live with a smoker, for example, have about a 20 to 30 percent greater risk of developing lung cancer than do spouses of non-smokers. Non-smokers exposed to tobacco smoke in the workplace are also more likely to get lung cancer.

When lung cancer first develops, there may be no symptoms. But as the cancer grows, it can cause changes including:

• a cough that doesn't go away and gets worse over time
• constant chest pain
• coughing up blood
• shortness of breath, wheezing or hoarseness
• repeated problems with pneumonia or bronchitis
• swelling of the neck and face
• loss of appetite or weight loss
• fatigue

These symptoms can be caused by lung cancer or by other conditions. It is important to consult your physician immediately if you experience any of the symptoms listed. Early detection is essential in the effective treatment of any disease, including lung cancer.
