The median survival time for those with stage 4 lung cancer is around four months, which means that 50% of patients will still be alive four months after their diagnosis. Lung cancer is classified as "small cell" or "non-small-cell," which Flores says is defined by "how the cancer … In this article, we look at the different staging systems for the main types of lung cancer, how they affect the outlook, and an overview of symptoms and diagnosis.
