What is Lung Cancer?

Lung cancer is cancer that starts in the lungs. When a person has lung cancer, they have abnormal cells that cluster together to form a tumor. Unlike normal cells, cancer cells grow without order or control, destroying

the healthy lung tissue around them. These types of tumors are called malignant tumors. When the cancer cells spread, they prevent organs of the body from functioning properly.


What Are the Types of Lung Cancer?


There are two main types of lung cancer: small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC). A third less common type of lung cancer is called carcinoid.


What Causes Lung Cancer?


Anyone can get lung cancer. Lung cancer happens when cells in the lung mutate or change. Various factors can cause this mutation (a permanent change in the DNA sequence of a gene) to happen. Most often, this change in lung cells happens when people breathe in dangerous, toxic substances. Even if you were exposed to these substances many years ago, you are still at risk for lung cancer.
