Types of lung cancer
Lung cancer is found in one or both of your lungs. How big the cancer is, if it's spread and your general health will all play a part in how serious it is.
There are two main types, with different treatments for each.
Non-small-cell lung cancer: the most common type, making up more than 80% of cases.
Small-cell-lung cancer: a less common type that usually spreads faster than non-small-cell lung cancer.
You're also more likely to be diagnosed with lung cancer if you smoke and are aged 75 or over.
