Still, lung cancer continues to be a very serious illness, especially when diagnosed at a later stage.
Once confirmed, the staging of the cancer needs to be completed.
Staging refers to determining how far cancer has spread in the body.

Stages are numbered from stage 0 to stage 4, the most advanced.
This number will be included in the diagnosis.
The exact treatment of lung cancer depends on what stage the cancer is, among other factors.
Typically, stage 4 lung cancer is not considered to be curable, though there are treatments available.
The treatment options for each stage may vary.
Some lung cancers grow slowly, while others are aggressive and grow quickly.
Different measures are involved in understanding lung cancer progression.
They include:
Survival ratedecreases for cancers of higher stages.
Although the cancer growth rate may be unpredictable, the end-of-life process follows a somewhat expected pattern.
This process can happen over days to a few weeks.
Treatments may extend a persons life for a period of months to even years.
It is staged from stage 0 to stage 4, reflecting growth and spread.
Life expectancy decreases as the stage increases.
Talk with your healthcare provider if you have questions about lung cancer symptoms and progression.
