Lung cancer is a type of cancer that begins in the lungs and does not usually cause noticeable symptoms until it's spread through the lungs or into other parts of the body. This means the outlook for the condition is not as good as many other types of cancer.
Are you at risk?
Exposure to a natural radioactive gas called radon can also heighten your risk of developing lung cancer, according to the NHS.
The gas comes from tiny amounts of uranium present in all rocks and soils and it can sometimes be found in building, according to the health site.
If radon is breathed in, it can damage your lungs, particularly if you're a smoker, although it only causes a small number of lung cancer deaths in England, says the health body.
