The survival rate over a five-year period simply determines the likelihood of a patient living five years after diagnosis; many individuals do live far longer than just five years, however.
To determine the 5-year survival rate, doctors will inspect the experience of patients who had treatment at least five years prior. Advancements in the treatment for non-small cell lung cancer in that five years can greatly increase the chance for survival in the span of 5 years for new patients.
The stage of cancer is the determination of the rates below. It is important to keep in mind that the state your cancer is in at the time of diagnosis will not differ regardless of advancement of the cancer should this occur. Although cancer may spread or return, the determination is still of the same class as the first diagnosis. However, further information is given on the current status of the cancer. And based on this, treatment is changed based on the current status of the cancer.
