Small Cell Lung Cancer (SCLC) Success Rate
Small cell lung cancer accounts for roughly 13% of lung cancers and tends to spread early (often to the brain) and aggressively. 10 Roughly one-third of these cancers are diagnosed when they are considered "limited stage" tumors, and two-thirds are already extensive at the time of diagnosis. 11
Non-Small Cell Lung Cancer (NSCLC) Success Rate
The effects of treatments for non-small cell lung cancer are reported in different ways. In some cases, these are divided by the four stages of the disease. In others, they are roughly broken down into three stages: local tumors (stage 1 and some stage 2 tumors), regional (some stage 2 and some stage 3 tumors), and distant (stage 4 lung cancer).
Influencing Factors
There are a number of factors that can influence the success rate of radiation therapy, and it's important to keep these in mind when looking at general statistics that compare people as a whole.
