About Lung Cancer

Lung cancer is a malignant tumor in the lungs. This means that the abnormal cells of the tumor grow without order or control. They destroy the healthy lung tissue around them.

Although some progress has been made in the treatment of lung cancer, it is still the most common cause of cancer death. In 2010, more than 222,000 new cases were expected to be diagnosed and about 157,000 Americans were expected to die from lung cancer.

The American Lung Association has developed this section of information for people living with lung cancer. We know that the more you learn about lung cancer, the better you and your loved ones can manage living with this disease, making the most of every day, and maintain the quality of life that is important to you.

There are many resources available to people living with lung cancer. The American Lung Association and our partners have provided information and tools created especially for you to use. Please explore the offerings here and in the other areas of our Lung Cancer section.

Early detection of lung cancer can increase survival rates. Call the Lung Helpline at 1-800-LUNGUSA or talk to your doctor about lung cancer screening.
