Treatment depends on the type of cancer, how far it's spread and how good your general health is.
If the condition is diagnosed early and the cancerous cells are confined to a small area, surgery to remove the affected area of lung is usually recommended.

Lung cancer doesn't 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 isn't as good as many other types of cancer.
Overall, about 1 in 3 people with the condition live for at least a year after they're diagnosed and about 1 in 20 people live at least 10 years.
However, survival rates can vary widely, depending on how far the cancer has spread at the time of diagnosis. Early diagnosis can make a big difference.
