Symptoms of COPD and Other Lung Diseases You Shouldn't Ignore - AARP

2. A cough that won't go away — and won't get better

It's not uncommon for a routine respiratory infection to cause a cough that sticks around for a few weeks — maybe even longer. But if your cough prevails and doesn't get better over time, "then it's something to be a little bit more concerned about," Wang Memoli says.

The American Lung Association recommends getting checked out if you have a cough that lasts more than eight weeks. Also, see a doctor if you're coughing up mucus or phlegm for more than a month. Coughing up blood is another red flag that shouldn't be ignored, says Gerard J. Criner, M.D., director of Temple Lung Center in Philadelphia. 

3. Chest pain or tightness

While often thought of as a cardiovascular issue, pain or tightness in the chest can be related to pulmonary complications, Wang Memoli says.

A sharp stabbing pain that hits when you breathe in or cough could point to pneumonia. And chest tightness is a common symptom of COPD, which is when the airways become damaged (less air flows in and out), making it hard to breathe. Emphysema and chronic bronchitis are the two most common conditions that contribute to COPD. 

Spotting symptoms early could improve treatment odds

Many conditions that fall under the lung disease umbrella are treatable or manageable with medications and other therapies, Wang Memoli says. In some cases, like with lung cancer, the second most common cancer in the U.S., early detection "results in improvement in survival," Criner says. Finding lung cancer early, when it's more curable, can decrease mortality by up to 20 percent, research shows.

And in other diseases, like COPD, which affects some 16 million Americans, "if you intercede and treat patients, they have a much better quality of life," Criner adds. Treatment for COPD may include medicines like bronchodilators to relax the muscles around the airways and steroids to reduce inflammation. Some people with COPD may also receive oxygen therapy.  

During an evaluation, your doctor will likely ask about your work history and other possible exposures, since everything from air pollution to smoking can cause lung disease.
