Lung Cancer

What is Lung Cancer?

Lung cancer is the most common cause of cancer related death, killing more people than breast, colon, and prostate cancer put together. Lung cancer is the biggest cancer killer in both men and women and smoking is the most common cause of it. Cigarette smoking is the single most preventable cause of death in the United States.1 Lung cancer primarily occurs in the elderly as 2/3 of diagnosed are 65 years or older.2

Here are some key statistics:

Types of Lung Cancer

Lung cancer types are determined by the sort of cells in the cancer. There are two main types:

1.) Non-Small Cell Lung Cancer - Approximately 85% of lung cancer cases are non-small cell lung cancer, which makes it the most common type of lung cancer. This type of cancer progresses less rapidly than small cell lung cancer.4

 

2.) Small Cell Lung Cancer

 

Small cell lung cancer is the deadliest form of lung cancer7 and is almost exclusively found in heavy smokers. This type of cancer grows quickly and spreads to other organs.8 This cancer usually starts in the air tubes (bronchi) in the center of the chest and grows quickly. Small cell lung cancer creates large masses (tumors) that can rapidly spread to other parts of the body, including the brain, liver, and bone.9
