Find answers to the 25 most frequently asked questions about lung cancer.

Asthma is a chronic (long-term) lung disease that inflames and narrows the airways. This makes the airways swollen and very sensitive. They tend to react strongly to certain substances that are breathed in.

When the airways react, the muscles around them tighten. This causes the airways to narrow, and less air flows to your lungs. The swelling also can worsen, making the airways even narrower. Cells in the airways may make more mucus than normal. (Mucus is a sticky, thick liquid that can further narrow your airways.)

COPD is a serious lung disease that over time makes it hard to breathe. Its official name is Chronic Obstructive Pulmonary Disease, but COPD has other names, like emphysema or chronic bronchitis.
